Public bug reported: I am using ubuntu 18.04 LTS. After an automatic update of libcups (and related) from 2.2.7-1ubuntu2 to 2.2.7-1ubuntu2.1 I have been unable to print double-sided, e.g., printing a pdf from evince using the standard printer dialog. I have not changed the printer or printer drivers during this and before everything was working fine.
I suspect that the option that is used for duplex printing is has changed and is wrong now. It seems to be "DuplexNoTumble", see $ lpoptions -l | grep -i duplex Duplex/Duplex: *None DuplexNoTumble DuplexTumble After using evince and the standard printer dialog to issue a print job where I selected "Long Edge (standard)" for the "Two Sided" option, I see the following in the cups error log: $ cat /var/log/cups/error_log | grep -i duplex D [20/Jul/2018:09:30:36 +0200] [Job 39] argv[5]="RPSBitsPerPixel=1BitsPerPixel InputSlot=Auto RPSRGBcorrect=DetailBright RPSDitherType=Auto RIwmSize=36 RIBannerPageMediaType=Auto LockedPrintPassword=None RIWMText=Confidential Rcmyksimulation=Off RIwmAngle=45Deg Booklet=None RPSColorRendDict=Auto RIPaperPolicy=PromptUser RPSBlackMode=gray noRPSColorUniversalDesign PageSize=A4.FullBleed JobType=Normal noRIBannerPagePrint RIPrintMode=0rhit MediaType=Auto RIRotateBy180=Off RIwmTextStyle=Gray RIPunch=None RIBannerPageInputSlot=Auto ColorModel=Gray Rimagesm=Off number-up=1 noRPSBlackOverPrint RIOrientOvr=Off StapleLocation=None Resolution=600dpi DocServerPassword=None RPSColorSep=None RIFoldType=None UserCode=None noCollate Duplex=DuplexNoTumble RIwmFont=HelveticaB RIWatermark=Off OutputBin=Default job-uuid=urn:uuid:10bf31c1-fbcf-31fd-4093-04b4cc248849 finishings=53 job-originating-host-name=localhost date-time-at-creation= date-time-at-processing= time-at-creation=1532071836 time-at-processing=1532071836" D [20/Jul/2018:09:30:36 +0200] [Job 39] Added option Duplex D [20/Jul/2018:09:30:36 +0200] [Job 39] Pondering option \'Duplex=DuplexNoTumble\' D [20/Jul/2018:09:30:36 +0200] [Job 39] Running command line for pstops: pstops 39 username \'filename\' 1 \'RPSBitsPerPixel=1BitsPerPixel InputSlot=Auto RPSRGBcorrect=DetailBright RPSDitherType=Auto RIwmSize=36 RIBannerPageMediaType=Auto LockedPrintPassword=None RIWMText=Confidential Rcmyksimulation=Off RIwmAngle=45Deg Booklet=None RPSColorRendDict=Auto RIPaperPolicy=PromptUser RPSBlackMode=gray noRPSColorUniversalDesign PageSize=A4.FullBleed JobType=Normal noRIBannerPagePrint RIPrintMode=0rhit MediaType=Auto RIRotateBy180=Off RIwmTextStyle=Gray RIPunch=None RIBannerPageInputSlot=Auto ColorModel=Gray Rimagesm=Off noRPSBlackOverPrint RIOrientOvr=Off StapleLocation=None Resolution=600dpi DocServerPassword=None RPSColorSep=None RIFoldType=None UserCode=None Duplex=DuplexNoTumble RIwmFont=HelveticaB RIWatermark=Off OutputBin=Default job-uuid=urn:uuid:10bf31c1-fbcf-31fd-4093-04b4cc248849 finishings=53 job-originating-host-name=localhost date-time-at-creation= date-time-at-processing= time-at-creation=1532071836 time-at-processing=1532071836\' D [20/Jul/2018:09:30:37 +0200] [Job 39] slow_collate=0, slow_duplex=0, slow_order=0 D [20/Jul/2018:09:30:37 +0200] [Job 39] Found: %%BeginFeature: *Duplex DuplexNoTumble D [20/Jul/2018:09:30:37 +0200] [Job 39] Option: Duplex=DuplexNoTumble Moreover, when trying to print from console I discovered that $ lp -o Duplex=DuplexNoTumble whatever.pdf prints single-sided, whereas $ lp -o sides=two-sided-long-edge whatever.pdf successfully prints double-sided. ** Affects: cups (Ubuntu) Importance: Undecided Status: New ** Tags: duplex -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782719 Title: Duplex not working upon update to 2.2.7-1ubuntu2.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1782719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
