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 +>Migration to from Samba 2.0.x to 2.2.x</H1 ><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 +>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 ><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 -><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.
