Any file arriving from Windows is -"auto-typed" by CUPS, which might consecutively lead to its -treatment by various filters automatically (depending on the -actual outcome of the auto-typing and the configuration of the -printqueue in question): - - --> Files generated by PCL drivers and destined to PCL - printers get auto-typed "application/octet-stream" - and are indeed printed "raw". Also, unknown file - types are getting tagged as "application/octet-stream". - - --> Files generated by a PostScript driver (and destined - for any target printer type) are auto-typed. Depending - on the driver, the discovered MIME type may be - - * application/postscript or - * application/vnd.cups-postscript - -"application/postscript" goes first thru the "pstops" filter - (where also the page counting and accounting takes place - currently), and the outcome will be of MIME type - "application/vnd.cups-postscript". The pstopsfilter reads and - uses information from the PPD and inserts user-provided options - into the PostScript file. As a consequence, the filtered file - will possibly have the PJL header you don't want. - -"application/postscript" will be all files with a ".ps", ".ai", - ".eps" suffix or which have as their first character string one - of "%!" or "<04>%". - -"application/vnd.cups-postscript" will be those files which do both, - first... - ...carry a string "LANGUAGE=POSTSCRIPT" (or similar variations - with different capitalization) amongst the first 512 bytes, - *plus*... - ...contain the "PJL super escape code" amongst the first 128 - bytes ("<1B>%-12345X"). Very likely, most PostScript files - generated on Windows using a CUPS- or other PPD, will have - to be auto-typed as "vnd.cups-postscript". - Probably a file produced with a "Generic PostScript driver" - will be just "application/postscript" (have not checked). - -Once the file is in "application/vnd.cups-postscript" format, -either "pstoraster" or "cupsomatic" will take over (depending -on the printer configuration, as determined by the PPD in use). - -NOTE: a printer queue with *no* PPD associated to it is a "raw" ------ printer and all files will go directly there as received - by the spooler; the exeption are file types -"application/octet-stream" which need the mentioned "passthrough -feature" enabled. "Raw" queues don't do any filtering at all, they -hand the file directly to the CUPS backend. This backend is -responsible for the sending of the data to the device (as visible -in the "device URI" notation as lpd://, socket://, smb://, ipp://, -http://, parallel:/, serial:/, usb:/ etc.) - -NOTE, please, also the following fact: "cupsomatic"/Foomatic are ------ *not* native CUPS drivers and they don't ship with CUPS. - They are a Third Party add-on, developed at Linuxprinting.org. -As such, they are a brilliant hack to make all models (driven by -Ghostscript drivers/filters in traditional spoolers) also work via -CUPS, with the same (good or bad!) quality as in these other -spoolers. "cupsomatic" is only a vehicle to execute a ghostscript -commandline at that stage in the CUPS filtering chain, where -"normally" the native CUPS "pstoraster" filter would kick in. -cupsomatic by-passes pstoraster, "kidnaps" the printfile from CUPS -away and re-directs it to go through Ghostscipt. CUPS accepts this, -because the associated CUPS-O-Matic-/Foomatic-PPD carries a line -reading - - *cupsFilter: "application/vnd.cups-postscript 0 cupsomatic" - -This line persuades CUPS to hand the file to cupsomatic, once it -has successfully converted it to the MIME type -"application/vnd.cups-postscript". This conversion will not -happen for Jobs arriving from Windows which are autotyped -"application/octet-stream", with the according changes in -"/etc/cups/mime.types" in place. - -See small drawings at the end... - -I am not a programmer, so please correct me if I am wrong. - - > With traditional lpr, you can just add "-oraw" to the "print command" - > line in smb.conf. With cups, you don't have that alternative. - -You *do* have it, I think. - -But you need to disable the settings "printing = cups" and "printcap = -= cups" and use "printing = bsd" and "printcap = /etc/printcap" -instead. [Additionally, you will probably have to enable and configure -the CUPS mini-LPD daemon ("cups-lpd") run from inetd... but I have not -checked, so take this item with a grain of salt and a proper dose of -caution, please.] - - > The result is that to support both unix printing and native-driver - > Windows printing from CUPS, you have to have two logical printers per - > physical printer: one ("cooked") for Unix clients and one ("raw") for - > Samba to use. - -Yes, that is one current workaround, if you don't want the auto-typing -of CUPS influencing Samba/Windows client PostScript jobs. - -CUPS is widely configurable and flexible, even regarding its filtering -mechanism. Another workaround in some situations would be to have -lines in "/etc/cups/mime.types" saying - - application/postscript application/vnd.cups-raw 0 - - application/vnd.cups-postscript application/vnd.cups-raw 0 - - -This would prevent all Postscript files to be filtered (or rather, they -will go thru the virtual "nullfilter" denoted with "-". (This could only -be useful for PS printers, or if you want to print PS code on non-PS -printers ;-) - -A single line of - - */* application/vnd.cups-raw 0 - - -would effectively send *all* files towards the backend immediately -(good luck!) - -Last, you could have the following (without the need for a Samba -patch): - - application/vnd.cups-postscript application/vnd.cups-raw 0 my_PJL_stripping_filter - -You'd need to write a "my_PJL_stripping_filter" (could be a shellscript) -which parses the PostScript and removes the undesired PJL. This would -need to conform to CUPS filter design (mainly, receive and pass the -parameters printername, job-id, username, jobtitle, copies, printoptions -and possibly the filename). It would just go as world executably into -"/usr/lib/cups/filters/" and work from there, called by cups if it -encounters a MIME type "application/vnd.cups-postscript" - - > The attached patch allows you to specify an option string for cups - > printers in smb.conf. - -I think your patch is in any case very useful (if it works as -advertised ;-).

You can add any other options that cups and the printer - > understand. - -Now this last sentence makes me very curious. Do you mean you can add -*multiple* options to this directive? Which syntax would be required -for this ? (Some CUPS options are specified by an "-o option=value" -pair on the commandline, some are single values, like the "-o raw" -one...) - -I am thinking on one specific usage now: - ------------------------------------------------------------------------ --> passing any available IPP job attribute to the printer / the spooler ------------------------------------------------------------------------ - -For example, CUPS can handle "-o job-hold-until=indefinite". This -keeps the job in the queue "on hold". It will only be printed upon -manual release by the printer operator.

(The operators often need to -load the proper paper type before running the 10.000 page job -requested by marketing for the mailing, etc.). - -A lot more useful applications come to mind, if I could pass -"any other options that cups and the printer understand" via -the smb.conf directive!! - -Thanks a lot! - -Cheers, -Kurt - -P.S.: List, please give me some feedback, if you think this type of - explanation could be useful in the Samba HOWTO Collection.

The output of this driver was not always -passed thru the "pstops" filter on the CUPS/Samba side, and therefor was -not counted correctly (the reason is that it often --- depending on the -"PPD" being used --- did write a "PJL"-header in front of the real -PostScript which made CUPS to skip the pstops and go directy to -the "pstoraster" stage). - - From CUPS-1.1.16 onward you can use the "CUPS PostScript Driver -for Windows NT/2K/XP clients" (it is tagged in the download area of -http://www.cups.org/ as the "cups-samba-1.1.16.tar.gz" package). -It is *not* working for Win9x/ME clients.

(Maybe one day before the 3.0 release it will -end up as a worked-out paragraph inside the HOWTO collection): - -You can download the driver files from http://www.cups.org/software.html. It -is a separate package from the CUPS base software files, tagged as "CUPS 1.1.16 -Windows NT/2k/XP Printer Driver for SAMBA (tar.gz, 192k)". The filename to -download is "cups-samba-1.1.16.tar.gz". Upon untar-/unzip-ping it will reveal -the files - - cups-samba.install - cups-samba.license - cups-samba.readme - cups-samba.remove - cups-samba.ss - -These have been packaged with the ESP meta packager software "EPM". The -*.install and *.remove files are simple shell script, which untars the -*.ss (which is nothing else than a tar-archive) and puts its contents -into "/usr/share/cups/drivers/". Its contents are 3 files: - - cupsdrvr.dll - cupsui.dll - cups.hlp - -[ ATTENTION: due to a bug the current release puts the "cups.hlp" into - "/usr/share/drivers/" instead of "/usr/share/cups/drivers/". To work - around this, copy/move the file after running the "./cups-samba.install" - script manually to the right place: - - "cp /usr/share/drivers/cups.hlp /usr/share/cups/drivers/" ] - -This new CUPS PostScript driver is currently binary-only, but free (as in -free beer); no source code is provided (yet). The reason is this: it has -been developed with the help of the Microsoft Driver Developer Kit (DDK) -and compiled with Microsoft Visual Studio 6. It is not clear to the driver -developers if they are allowed to distribute the whole of the source code -as Free Software. However, they will likely release the "diff" in source -code under the GPL, so anybody with a license of Visual Studio and a DDK -will be able to compile for him/herself. - -Once you have run the install script (and possibly manually moved the -"cups.hlp" file to "/usr/share/cups/drivers/"), the driver is ready to be -put into Samba's [print$] share (which often maps to "/etc/samba/drivers/" -and contains a subdir tree with WIN40 and W32X86 branches), by running -"cupsaddsmb" (see also "man cupsaddsmb" for CUPS 1.1.16). [Don't forget to -put root into the smbpasswd file by running "smbpasswd" should you run -this whole procedure for the first time.] Once the driver files are in the -[print$] share, they are ready to be downloaded and installed by the -Win NT/2k/XP clients. - -NOTE 1: Win 9x/ME clients won't work with this driver. For these you'd - still need to use the ADOBE*.* drivers as previously. - -NOTE 2: It is not harming if you've still the ADOBE*.* driver files from - previous installations in the "/usr/share/cups/drivers/" directory. - The new cupsaddsmb (from 1.1.16) will automatically use the - "newest" installed driver (which here then is the CUPS drivers). - -NOTE 3: Should your Win clients have had the old ADOBE*.* files and the - Adobe PostScript drivers installed, the download and installation - of the new CUPS PostScript driver for Windows NT/2k/XP will fail - at first. - It is not enough to "delete" the printer (as the driver files - will still be kept by the clients and re-used if you try to - re-install the printer). To really get rid of the Adobe driver - files on the clients, open the "Printers" folder (possibly via - "Start --> Settings --> Control Panel --> Printers"), right-click - onto the folder background and select "Server Properties". A - new dialog opens; select the "Drivers" tab; on the list select - the driver you want to delete and click on the "Delete" button. - (This will only work if there is no single printer left which - uses that particular driver -- you need to "delete" all printers - using this driver in the "Printers" folder first...) - -NOTE 4: Once you have successfully downloaded the CUPS PostScript driver - to a client, you can easily switch all printers to this one - by proceeding as described elsewhere in the "Samba HOWTO - Collection" to change a driver for an existing printer.... - - -What are the benefits with the "CUPS PostScript driver for Windows NT/2k/XP" -as compared to the Adobe drivers? - -* no hassle with the Adobe EULA; no hassle with the question "where do I - get the ADOBE*.* driver files from?" - -* the Adobe drivers (depending on the printer PPD associated with them) - often put a PJL header in front of the core PostScript part of the print - file (thus the file starts with "<1B>%-12345X" or "<escape>%-12345X" - instead of "%!PS"). This leads to the CUPS daemon autotyping the - arriving file as a print-ready file, not requiring a pass thru the - "pstops" filter (to speak more technical, it is not regarded as the - generic MIME type "application/postscript", but as the more special - MIME type "application/cups.vnd-postscript"), which therefore also - leads to the page accounting in "/var/log/cups/page_log" not receiving - the exact mumber of pages; instead the dummy page number of "1" is - logged in a standard setup...) - -* the Adobe driver has more options to "mis-configure" the PostScript - generated by it (like setting it inadvertedly to "Optimize for Speed", - instead of "Optimize for Portability", which could lead to CUPS being - unable to process it....) - -* the CUPS PostScript driver output sent by Windows clients to the CUPS - server will be guaranteed to be auto-typed as generic MIME type - "application/postscript", thusly passing thru the CUPS "pstops" filter - and logging the correct number of pages in the page_log for accounting - and quota purposes... - -* the CUPS PostScript driver supports the sending of additional print - options by the Win NT/2k/XP clients, such as naming the CUPS standard - banner pages (or the custom ones, should they be installed at the time - of driver download), using the CUPS "page-label" option, setting a - job-priority and setting the scheduled time of printing (with the option - to support additional useful IPP job attributes in the future). - -* the CUPS PostScript driver supports the inclusion of the new - "*cupsJobTicket" comments at the beginnig of the PostScript file (which - could be used in the future for all sort of beneficial extensions on - the CUPS side, but which will not disturb any other application as those - will regard it as a comment and simply ignore it). - -* the CUPS PostScript driver will be the heart of the fully fledged CUPS - IPP client for Windows NT/2k/XP to be released soon (probably alongside - the first Beta release for CUPS 1.2). - -============================================================================== -<<< EXTANT 5 >>> -============================================================================== -Subject: Printing with Bells and Whistles -========================================= - -May I suggest a radically different approach to your problem? - -* Let the Windows Clients use a PostScript driver, to produce - PostScript as their print output sent towards the Samba print - server (just like any Linux or Unix Client would also use - PostScript to send to the server...) - -* make the Unix printing subsystem which is underneath Samba - convert the incoming PostScript files to the native print - format of the target printers (would likely be PCL? - I understand you have mainly HP models?) - -* You're afraid, that this would just mean a *Generic* PostScript - driver for the clients?

Once the incoming directory -managed by Samba, (set f.e. in the "path = /var/spool/samba" -directive in the [printers] section of "smb.conf"). Second is -the spool directory of your UNIX print subsystem. For CUPS it is -normally "/var/spool/cups/", as set by the cupsd.conf directive -"RequestRoot /var/spool/cups". - -I am not sure, which one of your directories keeps the files. - From what you say, it is most likely the Samba part. - -For the CUPS part, you may want to consult: - - http://localhost:631/sam.html#PreserveJobFiles and - http://localhost:631/sam.html#PreserveJobHistory and - http://localhost:631/sam.html#MaxJobs - -There are the settings described for your CUPS daemon, which -could lead to completed job files not being deleted. - -"PreserveJobHistory Yes" -- keeps some details of jobs in -cupsd's mind (well it keeps the "c12345", "c12346" etc. files -in the CUPS spool directory, which do a similar job as the -old-fashioned BSD-LPD control files). This is set to "Yes" -as a default. - -"PreserveJobFiles Yes" -- keeps the job files themselves in -cupsd's mind (well it keeps the "d12345", "d12346" etc. files -in the CUPS spool directory...). This is set to "No" as the -CUPS default. - -"MaxJobs 500" -- this directive controls the maximum number -of jobs that are kept in memory. Once the number of jobs -reaches the limit, the oldest completed job is automatically -purged from the system to make room for the new one. If all -of the known jobs are still pending or active then the new -job will be rejected. Setting the maximum to 0 disables this -functionality. The default setting is 0. - -(There are also additional settings for "MaxJobsPerUser" and -"MaxJobsPerPrinter"...) - -For everything to work as announced, you need to have three -things: - - * a Samba-smbd which is compiled against "libcups" (Check - on Linux by running "ldd `which smbd`") - - * a Samba-smb.conf setting of "printing = cups" - - * another Samba-smb.conf setting of "printcap = cups" - -Note, that in this case all other manually set printing-related -commands (like "print command", "lpq command", "lprm command", -"lppause command" or "lpresume command") are ignored and they -should normally have no influence what-so-ever on your printing. - -If you want to do things manually, replace the "printing = cups" -by "printing = bsd".

ALL of this branch is in this file -and there is no overlap between any two users (Unless you have '95 set up -to use a single common profile). - -[** lkcl: see jht's message for conditions under which an overlap can occur **] - -The HKEY_LOCAL_MACHINE branch is machine based, and shared by all users of that -machine. - - -[And now for a whole stack of caveats] - -1. User start menu paths are not stored in the registry (obviously) they're - a directory structure that located by settings in HKEY_LOCAL_USER. - - If you want start menues / desktop / favorites to be individual to a user - you must set up your user registry so these can be located individually. - The easiest tool to manage this is the policy editor. - -2. When you log onto 'Doze 95, it has to find the user registry. - - - If you have specified a common profile, a "default user" USER.DAT is used. - - If you have specified individualised profiles, then USER.DAT will be found - by the following formula: - - 1. if NET USE x: /HOME was used at startup, try for x:\USER.DAT (where - x: is any drive letter from A to Z. - if no USER.DAT is found go to step 3 - - 2. if no home is specified in a mapping, - ...\windows\profiles\username\USER.DAT is used. If no USER.DAT exists - go to step 3. - - 3. If neither of the previous two found a USER.DAT, then it will use - a prototype USER.DAT which it will later save to the above specified - path when the user logs out. - - The interesting thing here is that the prototype USER.DAT used here - is actually a copy of the last USER.DAT used on this machine. (This - may be the effect that the original poster is seeing) - - 4. As discussed above the start menu and desktop are specified in the - registry contained within USER.DAT. When a new USER.DAT is created - from a prototype, new directories are created for the start menu and - desktop ACCORDING TO HOW THE COPIED PROTOTYPE DEFINES THEM. - - So if the prototype USER.DAT says that start menu is in H:\Start Menu - but programs folder is C:\windows\start menu\programs, then the - H:\start menu will be created, and the existing machine programs - folder used. - - This means that is is important when creating roving profiles to get - your prototype USER.DAT and general user directory structure set up - exactly as you want it, and then make a copy of it that you know will - be safe from modification. When creating a new user you then copy - this prototype into the new user area, so that the new user doesn't - just inherit what the previous user had. - - -3. When you log onto 'Doze NT, it has to find the user registry. - - - NT is easier to see what's going on, but follows much the same rules as - '95. The big difference being that 'NT gets its profile location from - the login server when it's logged in. (On an NT system have a look at user - manager/user/profile - you will see that you can specify the user profile - path) Under NT3.51 this profile path was a path to NTuser.DAT, on 4.0 this - seems to be a path to a directory structure (haven't played with many NT4 - servers) - - I'm not sure how this works in samba, as I haven't yet tried the NT_DOM stuff - yet (Luke: I assume you have a keyword for this?) - -[lkcl: nt workstations should look in exactly the same places for things on - samba or other SMB servers as they do on an NT server, as long as that - SMB server looks like NT. if anyone finds that something fails, alert - us on samba@samba.org and we'll look into it]. - - When an NT system find a user without a NTuser.DAT, it copies from a - prototype that it stores especially for this purpose, so while unlike '95 - the user doesn't get whatever happened last on the machine, the user will - get a fairly minimalist configuration. - -[[jht: -When a Win95 machine logs onto a Windows NT Domain the Win95 machine looks -for the presence of a file called Config.Pol in the following location: - \\"Authenticating Server"\NETLOGON -It reads this file and uses it to ammend both the desktop environment as well -as the file %WinDir%\Profiles\%USERNAME%\User.DAT. As with Windows NT, on log -out this file gets written back to the profile server into the %USERNAME% -directory in the profile share. - -It is thus possible to share a common desktop profile between Windows NT and -Windows 9x. -:jht]] - - -4. There are a *LOT* of reasons that the 'doze machine might not find USER.DAT - and therefore default to a prototype. - - 1. Can't execute logon script & therefore no /HOME mapping (Most common) - .Make sure the script exists - .that you have your logon script set right - .Netlogon share must exist - .Protection/ownership of the script and share - - 2. no /HOME mapping in the logon script - - 3. no home path specified in /etc/smb.conf (Or no home mapping set - up for that user in NT's user manager) - - 4. Protection/ownership of the user directory - - 5. protection/ownership of USER.DAT - - 6. basic networking problems - .Is the networking available (Test it by manually mapping - to both the user share and netlogon share) - .Was the networking working during logon ? - - 7. Has it defaulted to a prototype, and then had you map the home - directory afterwards ? - This will result in the bad prototype - being written into the users home, and them being stuck with it, - (Just replace USER.DAT again) - - -5. Interesting NOTE - - When '95 is performing the logon script, the HKEY_LOCAL_USERS has - NOT been mapped from the USER.DAT. What has been mapped at this stage - is the prototype registry (last one used). - - I assume the reason for this is that '95 is waiting for the logon - script to complete so that it can identify where the user's home - directory is. - - If at this point you attempt to do anything that uses the USER registry, - (installing something for example or reading something from the user - registry) you will actually be operating on the machine stored prototype - profile not the user profile. This means that nothing will realy - happen to the user setup (No menu items, no settings etc). - - To get around this you can name a process in the "run once" entries in - the HKEY_LOCAL_MACHINE branch, and these "run once" processes will be - executed once the USER.DAT is loaded, and all the user directories are - accessible. - - -To sum up: - - NET USE H: /HOME - is the key to getting your user profiles loaded from a server. - NET USE H: \\server\homes - Won't get it right without a lot of stuffing about. - - Windoze '95 goes through a lot to bring you your user profile and - if anything goes wrong during this process, it will drop back to - using whatever profile was last used on the machine. - - -From samba@aquasoft.com.au Sat Apr 11 13:48:54 1998 -Date: Sat, 11 Apr 1998 09:34:08 +1000 -From: Samba Bugs <samba@aquasoft.com.au> -To: Multiple recipients of list <samba-ntdom@samba.org> -Subject: Re: A question about NT Domains - -Just for the sake of completeness I thought I'd add a bit to this. -Let's be clear about which files affect registry changes (or contents). - -Under NT, open a command prompt interface: -cd %SystemRoot%\System32\config -dir - -The standard registry files are: - Default - all component default settings - System - all HKLM\System entries - Software - all HKLM\Software entries - Security - Domain/Machine releated User Rights & Privs. - SAM - the Security Access Manager database (ie:Passwords etc.) - -[[jht: -The SAM and Security files are the only files that get synchronised between -Windows NT Domain Controllers. -:jht]] - -These are used by EVERYTHING!! - -When a user logs in the following files get checked: - 1) \\"Authenticating Server"\NETLOGON\NTConfig.Pol - 2) %SystemRoot%\Profiles\Policies\NTConfig.Pol - this one is a copy of the last NTConfig.Pol downloaded - from (1) above - if available. - 3) %SystemRoot%\Policies\%UserName%\NTUser.DAT - -[[jht: -The System Policy Editor on Windows NT can be used to create both the -Windows 95 "Config.Pol" file, as well as the Windows NT "NTConfig.Pol" -file.

Yes, but not if correctly configured. - -> -> Q: Is this discussion out of place on the samba-ntdom list? -> A: Errr.... - -Errr... Really? I think it is. Do we, or do we not, want to help people to -gain stable and dependable use of samba? - -> -- -> Wolfgang Ratzka (dialing in from home) - -Cheers, -John H Terpstra (Also from home!!!!) - -============================================================================= -Further notes by Bruce Cook - -Date: Sun, 12 Apr 1998 14:12:22 +1000 -From: Bruce Cook <BC3-AU@bigfoot.com> -Subject: Re: Win95 / NT Profiles (was: RE: A question about NT Domains) - -Ah yes I knew there was something I forgot. -here it is for completeness. - -============================================================================= - -When a user logs into a specific machine for the first time, they will be -told that they've never logged into the machine, and would they like to -store the user setting for future use. - -If the user answers NO, they will be nagged about this every time they -log into the machine until they say YES. (How about it MS, could we -possible do something about this feature?) - -When the user answers YES, thereafter upon logging out of the machine, -a copy of the user's profile is also written onto the machines local disk -for later use. - -When a user logs into a machine where his/her profile has previously been -saved, a comparison is made between the date of the profile copy kept on -the machine, and the date of the profile stored on the server. In theory -the server date should be later or the same. - -If the local machine date is later than the server date, the client -machine will tell you the the settings on the local machine are more -recent than those of the server, and would you like to user them instead. - -This occurs for a couple of reasons: - 1. Server not available when the user logs out - 2. Date mismatch between the server and the client - (I always use NET TIME \\server /SET /YES in my logon scripts) - - -Logging in with NO server available. - -In some cases a client will want to log into a network with no server -available. (Portables away from the office, or a dead server) - -This can only happen if the administrator has NOT set the machine to -give access only upon password verification from the server. -(If the admin has done this, it can be circumvented by restarting - the machine in safe mode, and running poledit, or regedit and - disabling that feature) - -If you are able to log in while the server is unavailable, you have -two choices - 1. Log in as a user that previously stored a profile - (The password won't have to match unless the machine - is set up to store passwords) - - 2. log in as the default user (bit the cancel button or escape key) - -If you choose to use your profile stored on the local machine, there are -several things you should be wary of: - 1. the profile stored on the machine will be a copy of the last - profile used when you logged into THAT machine. You may get - quite an old profile. - 2. When you log out, that local profile is garunteed to be later - than the one on the server, and if the server is available, or - you later log into that machine when the server is available - you could overwrite the good server profile with a bogus profile. - - -Technique note: - I set portable computers up so that they don't use roaming profiles, - rather they have a single profile kept on the machine. This means - that a user has the same desktop look an feel regardless of where - they are. This follows the philosophy that laptops tend to be used - by only one person. |
