Spool to Lexmark m412 crashes on large images

[Kurt Pfeifle]

> I have a Linux machine which is a network print server for the office.  It receives print jobs from macs and Linux machines and prints to a Lexmark printer.  As long as I print text documents, it works fine.
>
> However, if I print anything which has large images on it ... Google maps, or most web pages, for example ... cups locks up and can't complete the print job.  The trigger really seems to be any print file which is too large.
>
> Current configuration is:
> Ubuntu 10.4 server
> Cups 1.3.9
> Lexmark m412 laser printer
> OSX 10.4 and 10.5 network print clients over IPP
>
> However, I had similar issues with the earlier config: SuSE 9.0 with the same printer.
>
> When I try to print something like a google map, what happens is:
>
> 1) The printing light starts flashing on the printer
> 2) The whole print spool locks up behind the stalled job
> 3) Eventually cups admin stops responding (after around 10-15 minutes)
> 4) I restart CUPS
> 5) I cancel the job
>
> Note that this printer will print large images fine when hooked directly to one of the macs, or to the Linux laptop.  This *appears* to be specifically an issue with network printing.

First, two questions:

  * Which 'driver' are you using?
       (this is determined by the PPD file which you find in
        /etc/cups/ppd/<printername>.ppd -- grep for all lines
        containing the "cupsFilter" keyword)

  * How is your Lexmark connected to the CUPS print server?
       ("lpstat -v" will output the 'backend' and its 'device URI',
       as it's called in CUPS-land.)
