Public bug reported:
Pages printed are not collated when I print a document with multiple
copies set and Collate option enabled on a printer without hardware
collate support.
Printer is Samsung ML-2950.
Operating systems affected are: Linux Mint 16, Ubuntu 13.04
CUPS filters pipe for printing a test text file is the following:
D [09/Dec/2013:14:34:00 +0400] [Job 16] texttopdf (text/plain to
application/pdf, cost 32)
D [09/Dec/2013:14:34:00 +0400] [Job 16] pdftopdf (application/pdf to
application/vnd.cups-pdf, cost 66)
D [09/Dec/2013:14:34:00 +0400] [Job 16] gstoraster (application/vnd.cups-pdf to
application/vnd.cups-raster, cost 99)
D [09/Dec/2013:14:34:00 +0400] [Job 16] rastertospl
(application/vnd.cups-raster to printer/test, cost 0)
rastertospl is proprietary filter, which converts CUPS raster data to
Samsung's SPL PDL.
PPD file is attached.
Further investigation has shown, that pdftopdf filter does not perform
software document copy generation with my PPD file set in environment
variable PPD, its output contains a single copy, but resulting CUPS
raster contains information about multiple copies and rastertospl
generates SPL output with mutiple copies for each page (uncollated).
pstops filter, started with the same CUPS job options set and multi-page
PostScript input, generates PostScript output with properly collated
pages.
pdftopdf has been executed with following parameters:
/usr/lib/cups/filter/pdftopdf 1 user "test" 2 "Collate" texttopdf.pdf >
pdftopdf.pdf
When I start pdftopdf with the same parameters, but with PPD environment
variable unset, it generates PDF file with document copies created.
When I modify PPD file by changing *cupsManualCopy attribute value to
True, pdftopdf produces collated output.
This printer supports hardware page copies, but does not support collate
in hardware.
It seems that pdftopdf filter logic used to determine collate method
does not handle this case correctly.
