the users. Samba can -provide this service reliably and seamlessly for a client network -consisting of Windows workstations. -</p><p> -A Samba print service may be run on a Stand-alone or Domain Member server, -side by side with file serving functions, or on a dedicated print server. -It can be made as tight or as loosely secured as needs dictate. Configurations -may be simple or complex. Available authentication schemes are essentially -the same as described for file services in previous chapters. Overall, -Samba's printing support is now able to replace an NT or Windows 2000 -print server full-square, with additional benefits in many cases. Clients -may download and install drivers and printers through their familiar -“<span class="quote">Point'n'Print</span>” mechanism. Printer installations executed by -“<span class="quote">Logon Scripts</span>” are no problem. Administrators can upload and -manage drivers to be used by clients through the familiar “<span class="quote">Add Printer -Wizard</span>”. As an additional benefit, driver and printer management may -be run from the command line or through scripts, making it more efficient -in case of large numbers of printers. If a central accounting of print jobs -(tracking every single page and supplying the raw data for all sorts of -statistical reports) is required, this function is best supported by -the newer Common UNIX Printing System (CUPS) -as the print subsystem underneath the Samba hood. -</p><p> -This chapter deals with the foundations of Samba printing as they -are implemented by the more traditional UNIX (BSD- and System V-style) -printing systems. Many things covered in this chapter apply also to CUPS. -If you use CUPS, you may be tempted -to jump to the next chapter but you will certainly miss a few things if -you do. It is recommended that you read this chapter as well as <link linkend="CUPS-printing">. -</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> -Most of the following examples have been verified on Windows XP -Professional clients. Where this document describes the responses to -commands given, bear in mind that Windows 200x/XP clients are quite -similar, but may differ in minor details. Windows NT is somewhat different -again. -</p></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2920765"></a>Technical Introduction</h2></div></div><div></div></div><p> -Samba's printing support always relies on the installed print subsystem -of the UNIX OS it runs on. Samba is a “<span class="quote">middleman.</span>” It takes -print files from Windows (or other SMB) clients and passes them to the real -printing system for further processing, therefore, it needs to communicate with -both sides: the Windows print clients and the UNIX printing system. Hence, we -must differentiate between the various client OS types, each of which behave -differently, as well as the various UNIX print subsystems, which themselves -have different features and are accessed differently. -</p><p> -This deals with the traditional way of UNIX printing. The next chapter -covers in great detail the more modern <span class="emphasis"><em>Common UNIX Printing -System</em></span> (CUPS). -</p><div class="important" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Important</h3><p>CUPS users, be warned: do not just jump on to the next -chapter. You might miss important information only found here! -</p></div><p> -It is apparent from postings on the Samba mailing list that print configuration -is one of the most problematic aspects of Samba administration today. Many -new Samba administrators have the impression that Samba performs some sort -of print processing. Rest assured, Samba does not peform any type of print -processing. It does not do any form of print filtering. -</p><p> -Samba obtains from its clients a data stream (print job) that it spools to a -local spool area. When the entire print job has been received, Samba invokes -a local UNIX/Linux print command and passes the spooled file to it. It is -up to the local system printing subsystems to correctly process the print -job and to submit it to the printer. -</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2920831"></a>Client to Samba Print Job Processing</h3></div></div><div></div></div><p> -Successful printing from a Windows client via a Samba print server to a UNIX -printer involves six (potentially seven) stages: -</p><div class="orderedlist"><ol type="1"><li><p>Windows opens a connection to the printer share.</p></li><li><p>Samba must authenticate the user.</p></li><li><p>Windows sends a copy of the print file over the network -into Samba's spooling area.</p></li><li><p>Windows closes the connection.</p></li><li><p>Samba invokes the print command to hand the file over -to the UNIX print subsystem's spooling area.</p></li><li><p>The UNIX print subsystem processes the print job.</p></li><li><p>The print file may need to be explicitly deleted -from the Samba spooling area.

Windows NT -permits the installation of local printers that are not shared. This is an artifact of the fact that -any Windows NT machine (server or client) may be used by a user as a workstation. Samba will publish all -printers that are made available, either by default or by specific declaration via printer-specific shares. -</p><p> -Windows NT/200x/XP Professional clients do not have to use the standard SMB printer share; they can -print directly to any printer on another Windows NT host using MS-RPC. This, of course, assumes that -the client has the necessary privileges on the remote host that serves the printer resource. The -default permissions assigned by Windows NT to a printer gives the Print permissions to the well-known -<span class="emphasis"><em>Everyone</em></span> group.

You can try to close all Windows file explorer -and Internet Explorer for Windows. As -a last resort, you may have to reboot. Make sure there is no automatic reconnection set up. It may be -easier to go to a different workstation and try from there.

Basically, the Device Mode and the set of Printer Driver Data is a -collection of settings for all print queue properties, initialized in a sensible way. Device Modes and -Printer Driver Data should initially be set on the print server (the Samba host) to healthy -values so the clients can start to use them immediately. How do we set these initial healthy values? -This can be achieved by accessing the drivers remotely from an NT (or 200x/XP) client, as is discussed -in the following paragraphs. -</p><p> -Be aware that a valid Device Mode can only be initiated by a -<a class="indexterm" name="id2927864"></a><i class="parameter"><tt>printer admin</tt></i>, or root -(the reason should be obvious). Device Modes can only be correctly -set by executing the printer driver program itself. Since Samba cannot execute this Win32 platform driver -code, it sets this field initially to NULL (which is not a valid setting for clients to use). Fortunately, -most drivers automatically generate the Printer Driver Data that is needed when they are uploaded to the -<i class="parameter"><tt>[print$]</tt></i> share with the help of the APW or rpcclient. -</p><p> -The generation and setting of a first valid Device Mode, however, requires some tickling from a client, -to set it on the Samba server. The easiest means of doing so is to simply change the page orientation on -the server's printer. This executes enough of the printer driver program on the client for the desired -effect to happen, and feeds back the new Device Mode to our Samba server. You can use the native Windows -NT/200x/XP printer properties page from a Window client for this: -</p><div class="procedure"><ol type="1"><li><p> - Browse the <span class="guiicon">Network Neighborhood.</span> - </p></li><li><p> - Find the Samba server. - </p></li><li><p> - Open the Samba server's <span class="guiicon">Printers and Faxes</span> folder. - </p></li><li><p> - Highlight the shared printer in question. - </p></li><li><p> - Right-click on the printer (you may already be here, if you followed the last section's description). - </p></li><li><p> - At the bottom of the context menu select <span class="guimenu">Properties</span> (if the menu still offers the - <span class="guimenuitem">Connect</span> entry further above, you - need to click on that one first to achieve the driver - installation as shown in the last section). - </p></li><li><p> - Go to the <span class="guilabel">Advanced</span> tab; click on <span class="guibutton">Printing Defaults</span>. - </p></li><li><p> - Change the <span class="guimenuitem">Portrait</span> page setting to <span class="guimenuitem">Landscape</span> (and back). - </p></li><li><p> - Make sure to apply changes between swapping the page orientation to cause the change to actually take effect. - </p></li><li><p> - While you are at it, you may also want to set the desired printing defaults here, which then apply to all future - client driver installations on the remaining from now on. - </p></li></ol></div><p> -This procedure has executed the printer driver program on the client platform and fed back the correct -Device Mode to Samba, which now stored it in its TDB files.

From now on, printing should work as expected. -</p><p> -Samba includes a service level parameter name <i class="parameter"><tt>default devmode</tt></i> for generating a default -Device Mode for a printer.

All three -dialogs look the same, but only one -of them does what you intend. You need to be Administrator or Print Administrator to do this for all -users. Here is how I reproduce it in an XP Professional: - -The following list needs periods after the letters and numbers::::::::: -</p><div class="orderedlist"><ol type="A"><li><p>The first “<span class="quote">wrong</span>” way: - </p><div class="orderedlist"><ol type="1"><li><p>Open the <span class="guiicon">Printers</span> folder.</p></li><li><p>Right-click on the printer (<span class="emphasis"><em>remoteprinter on cupshost</em></span>) and - select in context menu <span class="guimenu">Printing Preferences...</span></p></li><li><p>Look at this dialog closely and remember what it looks like.</p></li></ol></div></li><li><p>The second “<span class="quote">wrong</span>” way: - </p><div class="orderedlist"><ol type="1"><li><p>Open the <span class="guimenu">Printers</span> folder.</p></li><li><p>Right-click on the printer (<span class="emphasis"><em>remoteprinter on - cupshost</em></span>) and select in the context menu - <span class="guimenuitem">Properties</span></p></li><li><p>Click on the <span class="guilabel">General</span> - tab</p></li><li><p>Click on the <span class="guibutton">Printing - Preferences...</span></p></li><li><p>A new dialog opens.

I do not either. However, only the last one, which -you arrived at with steps C.1 through 6 will permanently save any settings which will then become the defaults -for new users. If you want all clients to have the same defaults, you need to conduct these steps as -administrator (<a class="indexterm" name="id2928716"></a><i class="parameter"><tt>printer admin</tt></i> in ) before -a client downloads the driver (the clients can later set their own per-user defaults -by following procedures A or B above). Windows 200x/XP allow per-user default settings and the ones the -administrator gives them, before they set up their own. The parents of the identically-looking dialogs have a slight difference in their window names; one is called <tt class="computeroutput">Default Print -Values for Printer Foo on Server Bar"</tt> (which is the one you need) and the other is called -“<span class="quote"><tt class="computeroutput">Print Settings for Printer Foo on Server Bar</tt></span>”. The last one is the one you -arrive at when you right-click on the printer and select <span class="guimenuitem">Print Settings...</span>.

The <b class="command">/q</b> at the end eliminates Confirm - or error dialog boxes from popping up.

The printer and its driver must have been added to Samba prior to - the user logging in (e.g., by a procedure as discussed earlier in this chapter, or by running - <b class="command">cupsaddsmb</b>).

It is triggered by running the APW from a client against the Samba print server. The APW asks -the user to fill in several fields (such as printer name, driver to be used, comment, port monitor, -and so on). These parameters are passed on to Samba by the APW. If the addprinter command is designed in a -way that it can create a new printer (through writing correct printcap entries on legacy systems, or -execute the <b class="command">lpadmin</b> command on more modern systems) and create the associated share -in, then the APW will in effect really create a new printer on Samba and the UNIX print subsystem! -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2930686"></a>Migration of Classical Printing to Samba</h2></div></div><div></div></div><p> -The basic NT-style printer driver management has not changed considerably in 3.0 over the 2.2.x releases -(apart from many small improvements). Here migration should be quite easy, especially if you followed -previous advice to stop using deprecated parameters in your setup. For migrations from an existing 2.0.x -setup, or if you continued Windows 9x/Me-style printing in your Samba 2.2 installations, it is more of -an effort. Please read the appropriate release notes and the HOWTO Collection for Samba-2.2.x. You can -follow several paths. Here are possible scenarios for migration: -</p><div class="itemizedlist"><ul type="disc"><li><p> - You need to study and apply the new Windows NT printer and driver support. Previously used - parameters <i class="parameter"><tt>printer driver file</tt></i>, <i class="parameter"><tt>printer driver</tt></i> - and <i class="parameter"><tt>printer driver location</tt></i> are no longer supported. - </p></li><li><p> - If you want to take advantage of Windows NT printer driver support, you also need to migrate the - Windows 9x/Me drivers to the new setup. - </p></li><li><p> - An existing <tt class="filename">printers.def</tt> file (the one specified in the now removed parameter - <i class="parameter"><tt>printer driver file</tt></i>) will no longer work with Samba-3. In 3.0, smbd attempts - to locate a Windows 9x/Me driver files for the printer in <i class="parameter"><tt>[print$]</tt></i> - and additional settings in the TDB and only there; if it fails, it will <span class="emphasis"><em>not</em></span> - (as 2.2.x used to do) drop down to using a <tt class="filename">printers.def</tt> (and all associated - parameters). The make_printerdef tool is removed and there is no backward compatibility for this. - </p></li><li><p>You need to install a Windows 9x/Me driver into the - <i class="parameter"><tt>[print$]</tt></i> share for a printer on your Samba - host. The driver files will be stored in the “<span class="quote">WIN40/0</span>” subdirectory of - <i class="parameter"><tt>[print$]</tt></i>, and some other settings and information go - into the printing-related TDBs.</p></li><li><p>If you want to migrate an existing - <tt class="filename">printers.def</tt> file into the new setup, the - only current - solution is to use the Windows NT APW to install the NT drivers - and the 9x/Me drivers. This can be scripted using smbclient and - rpcclient. See the Imprints installation client at: - </p><p> - <ulink url="http://imprints.sourceforge.net/">http://imprints.sourceforge.net/</ulink> - </p><p> - for an example.
