** Description changed: Certain images are substantially degraded when printing. The problem only occurs with Acrobat Reader on Ubuntu, not xpdf or Acrobat Reader on Windows 7 (using the same printer and input PDF). So there is something wrong with Acrobat Reader on Ubuntu specifically (or maybe any Linux). The printed image appears darkened or the available grey-scale resolution is lesssened. The test image (attached) is blueish and the printing was on a monochrome laser printer (hp3030), so the problem might be related to mapping colors to greyscale. The PDF was created by exporting from Libre Office Writer with PDF/A and "Lossless" image compression. Here are the exact versions of Acrobat Reader I tested: Windows 7 (32-bit): Acrobat Reader 9.5.0 [works] Ubuntu (both 64-bit & 32-bit): Acrobat Reader "9.5.1 03/07/2012" [image degraded when printed] - WORKAROUND: lpr AcrobatTestImage.pdf + POSSIBLE WORKAROUNDS: + To just print the whole file: lpr AcrobatTestImage.pdf + + To print only odd (or other selected) pages, for duplexing: + pdfjam -o file_odd.pdf file.pdf '1,3,5,7,9,11,...' && lpr file_odd.pdf + (There is no 'give me all odd pages' option to pdfjam so every page must be enumerated) --- ApportVersion: 1.23-0ubuntu4 Architecture: amd64 CupsErrorLog: W [11/May/2012:12:14:07 -0700] failed to AddProfile: org.freedesktop.ColorManager.Failed:profile object path '/org/freedesktop/ColorManager/profiles/hp_LaserJet_3030_Gray__' has already been added W [11/May/2012:12:14:07 -0700] failed to AddProfile: org.freedesktop.ColorManager.Failed:profile object path '/org/freedesktop/ColorManager/profiles/hp_LaserJet_3030_Fax_Gray__' has already been added W [11/May/2012:12:14:07 -0700] failed to AddProfile: org.freedesktop.ColorManager.Failed:profile object path '/org/freedesktop/ColorManager/profiles/hp_LaserJet_3030_Fax_RGB__' has already been added W [11/May/2012:12:14:07 -0700] failed to AddProfile: org.freedesktop.ColorManager.Failed:profile object path '/org/freedesktop/ColorManager/profiles/PDF_Gray__' has already been added W [11/May/2012:12:14:07 -0700] failed to AddProfile: org.freedesktop.ColorManager.Failed:profile object path '/org/freedesktop/ColorManager/profiles/PDF_RGB__' has already been added DistroRelease: Ubuntu 11.10 InstallationMedia: Xubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) Lpstat: device for hp-LaserJet-3030: hp:/usb/hp_LaserJet_3030?serial=00CNBM066305 device for hp-LaserJet-3030-Fax: hpfax:/usb/hp_LaserJet_3030?serial=00CNBM066305 device for PDF: cups-pdf:/ MachineType: System manufacturer System Product Name Package: cups 1.5.0-8ubuntu6 PackageArchitecture: amd64 Papersize: letter PpdFiles: hp-LaserJet-3030: HP LaserJet 3020 3030 Postscript (recommended) PDF: Generic CUPS-PDF Printer hp-LaserJet-3030-Fax: HP Fax hpcups ProcEnviron: PATH=(custom, user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.0.0-19-generic root=UUID=8aaca318-f079-4a4f-95c0-735aa54bed2d ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.0.0-19.33-generic 3.0.27 Tags: oneiric Uname: Linux 3.0.0-19-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm admin audio cdrom dialout dip fax floppy fuse games lpadmin netdev plugdev sambashare scanner sudo tape users vboxusers video dmi.bios.date: 09/21/2010 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 1408 dmi.board.asset.tag: To Be Filled By O.E.M. dmi.board.name: P6T dmi.board.vendor: ASUSTeK Computer INC. dmi.board.version: Rev 1.xx dmi.chassis.asset.tag: Asset-1234567890 dmi.chassis.type: 3 dmi.chassis.vendor: Chassis Manufacture dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr1408:bd09/21/2010:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKComputerINC.:rnP6T:rvrRev1.xx:cvnChassisManufacture:ct3:cvrChassisVersion: dmi.product.name: System Product Name dmi.product.version: System Version dmi.sys.vendor: System manufacturer
