Dave,

You are right.

Applications that generate their own PostScript call
PMSessionGetDocumentFormatGeneration() to get a list of available spool file
formats for the current printer. In Jaguar, calling
PMSessionGetDocumentFormatGeneration() when the current printer has a CUPS
driver, always returns kPMDocumentFormatPDF ("application/pdf") and
kPMDocumentFormatPICTPS ("application/vnd.apple.printing-pict-ps"). As you
state, this is obviously wrong when the driver associated with the current
printer cannot handle PostScript data. So, for example, if you have the
Gimp drivers installed WITHOUT the ESP-Ghostscript package, printing from
many Adobe applications will fail.

PMSessionGetDocumentFormatGeneration() gets its results from CUPS. The
problem is that CUPS returns a list of all the MIME types supported by the
installed filters, which includes our 'pictwpstops' filter. The fix
requires CUPS to return a list of supported MIME types on a per-queue basis.
We are working to make this change for a future release.

Will the fix spoken of here, having CUPS scan only filters which can be used
from the currently selected queue be in Panther?


Thanks,
Jim
