>Description:
The CUPS pdftops filter's "Produced by xpdf/pdftops..." header is inserted without
a postscript comment. This causes printing the job to fail on a wide range of
printers with an "Unknown operand: Produced" error or something similar.
>How-To-Repeat:
Print any pdf document using CUPS 1.2.
>Fix:
writePSFmt() uses sprintf(), which removes lone % signs (except on Linux, which
apparently is the only system on which ESP tested this). As such, the comment
prefix is removed and the job fails. Adding more % signs (there should properly
be two in the final output) fixes the problem.
