[cups-devel] CUPS job ticket confusion

Hi!

I am confused by how cups job tickets work as there is not that
detailed information available. My understanding is that it is
possible to insert %cupsJobTicket statements into PS and PDF files,
e.g.:

%PDF-1.5
%cupsJobTicket: sides=two-sided-long-edge

I tried with various files and options but none of them were applied.
Are there specific prerequisites? Which format of options is to be
used, PPD (e.g. InputSlot=Tray1) or IPP (e.g. media-source=tray-1) or
both?


Thanks and regards,

Stephan
