I recently upgraded to cups-1.2.12-r2 and ghostscript-gpl-8.60-r1 and since then duplex printing does not work any more. I tried downgrading to ghostscript-gpl-8.54, but the error persists. All printouts are single-sided, no matter which duplex-option i provide. BTW, I use a modified version of a generic PCL5c device, using ghostscript driver ljet4d. I set LogLevel to debug to check command line options, and they are correct. Reproducible: Always Steps to Reproduce: 1. print any document with multiple pages Actual Results: no duplex pages Expected Results: pages printed on both sides
(In reply to comment #0) I tried a PS-capable printer, and here duplex printing is OK, must be cups in combination with ghostscript ?

Which version of cups and ghostscript did you use before? Also what hardware are you using? > ghostscript-gpl-8.54, but the error persists.

I tried to reproduce this on a HP LaserJet 5100dtn with both - cups 1.2, using the "HP LaserJet Series PCL 4/5 CUPS v1.2" driver - cups 1.3, using the "HP LaserJet Series PCL 4/5, 1.3" driver then setting - Duplexer: Installed - Double-Sided Printing: Long-Edge (Standard) in the cups webinterface and was able to print doublesided, tested with a simple OOo Writer two page document. Can you also do a test with the same standard cups driver(s)?

Did you try the official one provided by Canon yet or is this not an option for you? I just tested with the PPD they offer on their site for the IR 3380 by downloading g7b1dex.tgz and using the cnrc288g1.ppd included in the package to configure a new cups printer and it also works with our HP printer single/duplex. However I'm not sure now if this driver uses PCL or postscript but could be worth a try.

Used "HP LaserJet Series PCL 4/5 CUPS v1.2" (since the Canon iR 3380 talks PCL5c I think) and printing works like a charm after enabling the duplexer unit. Strange, why duplex feature vanished for gs with driver ljet4d, even though the right options are set. I read something in the change logs of cups like removing duplex for single pages, maybe this has an unwanted side-effect. Nevertheless, printing is working correctly now, and I'm happy now. Thanks for your suggestions. Gerhard
