You're welcome! :-) As I said, I hope the strategy I found may help other users too. > I wonder whether you have > a PDF which is troublesome with the HP-LaserJet_1320-pxlmono.ppd > but is ok with HP/hp-laserjet_1320-ps.ppd and could send it here? Unfortunately I don't remember having ever found a troublesome PDF file which was generated by me or is otherwise redistributable without nasty restrictions. Misbehavior usually happens with PDF files produced by other people, probably with non-free tools. For instance: the one I used as a test case for the pdftops-renderer-default=pdftocairo strategy was created and produced with "Microsoft® Word 2010", according to the pdfinfo output. The PDF file originally sent by jaakov is instead generated by another tool: $ pdfinfo \ HensgenFinkelManber-TwoAlgorithmsForBarrierSynchronization.pdf [...] Creator: P06013001.TIF Producer: PageGenie PDFGenerator [...] Please note that I tested the Hensgen PDF file too, before finding the pdftops-renderer-default=pdftocairo strategy. As I have previously said, I got blank pages when not passing through cairo. I instead obtained a correct printout from zathura (which uses cairo). I haven't re-tested this file, but I suppose it will print correctly with pdftops-renderer-default=pdftocairo ... > > I did try jaakov's Hensgen PDF with your print queues and my printer > (an HP 2200DN) and had a a varied experience, which I will not bore > anyone with.

That's why I described cairo rendering as "more robust"! > > I do not think doing anything purposeful with the original bug report > is really possible without a PPD to work with. Maybe jaakov has some further feedback to send in. Let's wait and see. Bye. -- http://www.inventati.org/frx/ fsck is a four letter word... .....................................................
