Introduction</H2 +><P +>This is a short description of how to debug printing problems with +Samba. This describes how to debug problems with printing from a SMB +client to a Samba server, not the other way around. For the reverse +see the examples/printing directory.</P ><P ->Given that printer driver management has changed (we hope improved) in -2.2 over prior releases, migration from an existing setup to 2.2 can -follow several paths. Here are the possible scenarios for -migration:</P +>Ok, so you want to print to a Samba server from your PC. The first +thing you need to understand is that Samba does not actually do any +printing itself, it just acts as a middleman between your PC client +and your Unix printing subsystem. Samba receives the file from the PC +then passes the file to a external "print command". What print command +you use is up to you.</P ><P +>The whole things is controlled using options in smb.conf. The most +relevant options (which you should look up in the smb.conf man page) +are:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> [global] + print command - send a file to a spooler + lpq command - get spool queue status + lprm command - remove a job + [printers] + path = /var/spool/lpd/samba</PRE ></P -><UL +><P +>The following are nice to know about:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> queuepause command - stop a printer or print queue + queueresume command - start a printer or print queue</PRE +></P +><P +>Example:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> print command = /usr/bin/lpr -r -P%p %s + lpq command = /usr/bin/lpq -P%p %s + lprm command = /usr/bin/lprm -P%p %j + queuepause command = /usr/sbin/lpc -P%p stop + queuepause command = /usr/sbin/lpc -P%p start</PRE +></P +><P +>Samba should set reasonable defaults for these depending on your +system type, but it isn't clairvoyant. It is not uncommon that you +have to tweak these for local conditions. The commands should +always have fully specified pathnames, as the smdb may not have +the correct PATH values.</P +><P +>When you send a job to Samba to be printed, it will make a temporary +copy of it in the directory specified in the [printers] section. +and it should be periodically cleaned out. The lpr -r option +requests that the temporary copy be removed after printing; If +printing fails then you might find leftover files in this directory, +and it should be periodically cleaned out. Samba used the lpq +command to determine the "job number" assigned to your print job +by the spooler.</P +><P +>The %>letter< are "macros" that get dynamically replaced with appropriate +values when they are used. The %s gets replaced with the name of the spool +file that Samba creates and the %p gets replaced with the name of the +printer. The %j gets replaced with the "job number" which comes from +the lpq output.</P +></DIV +><DIV +CLASS="SECT2" +><H2 +CLASS="SECT2" +><A +NAME="AEN2099" +></A +>14.4.2. Debugging printer problems</H2 +><P +>One way to debug printing problems is to start by replacing these +command with shell scripts that record the arguments and the contents +of the print file. A simple example of this kind of things might +be:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> print command = /tmp/saveprint %p %s + + #!/bin/saveprint + # we make sure that we are the right user + /usr/bin/id -p >/tmp/tmp.print + # we run the command and save the error messages + # replace the command with the one appropriate for your system + /usr/bin/lpr -r -P$1 $2 2>>&/tmp/tmp.print</PRE +></P +><P +>Then you print a file and try removing it. You may find that the +print queue needs to be stopped in order to see the queue status +and remove the job:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> h4: {42} % echo hi >/tmp/hi +h4: {43} % smbclient //localhost/lw4 +added interface ip=10.0.0.4 bcast=10.0.0.255 nmask=255.255.255.0 +Password: +Domain=[ASTART] OS=[Unix] Server=[Samba 2.0.7] +smb: \> print /tmp/hi +putting file /tmp/hi as hi-17534 (0.0 kb/s) (average 0.0 kb/s) +smb: \> queue +1049 3 hi-17534 +smb: \> cancel 1049 +Error cancelling job 1049 : code 0 +smb: \> cancel 1049 +Job 1049 cancelled +smb: \> queue +smb: \> exit</PRE +></P +><P +>The 'code 0' indicates that the job was removed. The comment +by the smbclient is a bit misleading on this. +You can observe the command output and then and look at the +/tmp/tmp.print file to see what the results are. You can quickly +find out if the problem is with your printing system. Often people +have problems with their /etc/printcap file or permissions on +various print queues.</P +></DIV +><DIV +CLASS="SECT2" +><H2 +CLASS="SECT2" +><A +NAME="AEN2108" +></A +>14.4.3.

For example, you can +use:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> testprns printer /etc/printcap</PRE +></P +><P +>Samba can get its printcap information from a file or from a program. +You can try the following to see the format of the extracted +information:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> testprns -a printer /etc/printcap + + testprns -a printer '|/bin/cat printcap'</PRE +></P +></DIV +><DIV +CLASS="SECT2" +><H2 +CLASS="SECT2" +><A +NAME="AEN2116" +></A +>14.4.4.

This printcap information has the format:</P +><P +><PRE +CLASS="PROGRAMLISTING" +> name|alias1|alias2...:option=value:...</PRE +></P +><P +>For almost all printing systems, the printer 'name' must be composed +only of alphanumeric or underscore '_' characters. Some systems also +allow hyphens ('-') as well. An alias is an alternative name for the +printer, and an alias with a space in it is used as a 'comment' +about the printer.
