ulimit -t for ghostscript

[Christoph Litauer]

Environment:
Suse 8.2
Cups 1.1.18


I have lots of problems printing to a HP Laserjet 4000. Using the 
Windows 2000 ppd file I had some documents that produced postscript 
errors. So I decided to use foomatic for that printer (with ijs).
Sometimes, documents printed from windows clients cause ghostscript to 
take 100% cpu usage and run forever (ESP ghostscript 7.07.1).
Because in that case the printers queue is blocked with those jobs I 
want to limit the amount of cpu time for that gs process (started by 
foomatic-rip).
My first idea was writing a wrapper script:

#!/bin/bash
ulimit -t 180
exec gs "$@"

Then I changed the FommaticCommandLine in the printers ppd file to point 
to the wrapper script.
This worked perfectly good except for one thing: The output is prepended 
with the following lines

%%[ ProductName: ESP Ghostscript ]%%
%%[Page: 1]%%
%%[LastPage]%%

I wonder why this output does not appear if I don't use a wrapper. 
Anybody has an idea how to prevent those lines? Output redirection 
doesn't help because the lines and the ijs output are both written to 
stdout ...
