Re: [Printing-architecture] Different Collate option handling in pdftopdf and pstops

[Andrey Makhalkin <a.makhalkin@samsung.com>]

Dear Michael,

It is not a PDF printer.
I print to a raster printer using CUPS in Linux Mint 16(a VM for testing
purposes).
CUPS filters pipe 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.

Sincerely yours,
Andrey Makhalkin

And in fact it is a hard requirement for IPP Everywhere printers that support PDF.
