how to make cups ignore papersize?

[sinder at thp.uni-koeln.de]

Hi,

is there a way to tell cups that it should simply ignore the papersize
of the document to be printed and to send it to the printer "as is".
The printer itself is setup in such a way that it ignores the
papersize and will print the document.

The problem currently is that when sending documents of letter size via
cups to our printers they won't be printed (the printing machine starts
running (noise) but no paper is printed/ejected, ie. the Interpreter
doesn't seem to be successfull printing CUPS-generated jobs).

Whereas uploading them directly to the printer via the printer's
internal webserver they are printed without any problems even
though they have the wrong papersize.

We are using Xerox DocuPrint N4525 network printers with the
Xerox-DocuPrint_N32-Postscript.ppd  foomatic driver.

Do you have an idea how to make CUPS ignoring the papersize of a
print job?

Thanks in advance!
Andreas
