I recently wrote a filter for my employer's line of thermal-transfer
printers, which worked okay under Tiger, but now I get the following
error in the CUPS error log:
cgpdftoraster: got an error from cupsRasterInterpretPPD
I'm not sure why this happens, as everything worked great under Tiger.
This happens when upgrading from Tiger to Leopard, and when doing a
fresh/full install of Leopard. I have submitted this to the Apple
BugReporter (problem ID 5594485) and thought that perhaps some fellow
devs here on the mailing list might have some insight or clues as to
what's happening.
Run cupstestppd on your PPD file. More than likely your PPD file
contains bad PostScript code. You can also do:
cupsctl --debug-logging
in a Terminal window to get more information logged in the
error_log file.
Basically, cupsRasterInterpretPPD() is responsible for setting
the page device dictionary values - previously we just looked
for "/name value" pairs, but now we actually interpret a (small)
subset of PostScript to get the values. This is documented here:
