The conversion of a PDF to a PDF may be seen as unnecessary and unlikely to meet with universal approval. For example: https://www.bountysource.com/issues/1333719-printing-if-input-file-is-ps-file-gets-directly-passed-to-cups-if-it-is-pdf-an-ugly-rerendering-happens You may do this for yourself if you want by having 'pdftocairo -pdf' in your workflow. > > In fact, lp and lpr send identical PDFs so > > a poor output for lpr should also be a poor output for lp.

I think that lp and lpr have the same set of options. Anyway, my point (not very well made) was that the lpr command itself and cups-bsd are not the problem, so I am reassigning the bug to cups-filters with a Cc to Till K to ascertain whether buggy printer interpreters could be an issue. > Anyway, I tested the two files originally sent by jaakov [1], and I get > blank pages when printing > HensgenFinkelManber-TwoAlgorithmsForBarrierSynchronization.pdf with > lpr, as reported by jaakov at the time. I have no printer available for the next few days. I'll try the same PDF when I can. > [1] the two attachments of https://bugs.debian.org/613987#5 > > > We could do with knowing what printers are used, their PPDs and how they > > are connected. > > Two examples. > > HP LaserJet 1320n > ----------------- > connected via Ethernet LAN and configured with the following commands: > > # lpadmin -p lj -E -v lpd://x.y.z.w/lp0 \ > -m foomatic:HP-LaserJet_1320-pxlmono.ppd \ > -o pdftops-renderer=pdftops \ > -D "HP LaserJet 1320" > # lpoptions -p lj -o media=A4 -o sides=two-sided-long-edge That PPD outputs HP Printer Job Language and not PostScript. I don't think -o will have any effect. It could be used with the Phasor though. Regards, Brian. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
