@5 I can't try, because as I already mentioned, I fixed the issue long ago by reinstalling the printer.
However, I can see how the printer icon looks like if I unckeck the "enabled" item in the context menu: a "pasue"-like symbol show up over the printer, and this was NOT the case when the bug happened. Also note I had rebooted several times, and switched the printer off and on, and disconnected and reconnected it. All of these should definitely reset whatever printer status needs to reset, and if they don't, something is broken. So whether or not manually "resuming" the printer would work (which I'm 99% sure it wouldn't, as it was not shown as paused), that doesn't in any case change the fact that this is a bug. ** Changed in: cups (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1250407 Title: printer has stopped working. "Filter failed" Status in “cups” package in Ubuntu: Confirmed Bug description: My printer was working fine until yesterday. A printing job was interrupted with a good reason because I disconnected the usb. However, I then reconnected the printer and rebooted, and cancelled the pending job. Now the printer doesn't print any more. Whenever I try, the printer icon appears in the notification area, and if I click on it, the printer is listed as "paused". If I select it, the "Document print status" shows the job as "pending". If I go to "Printers", the printer is shown with a green checkmark. If I double click it to see "Printer Properties", under the "Settings" tab, under "Printer State" it says: "Stopped - Filter failed" Unplugging and replugging the printer doesn't fix the issue, nor does turning it off and on again, cancelling and restarting the printing job. $ cat /var/log/cups/error_log W [12/Nov/2013:01:27:24 +0100] CreateProfile failed: org.freedesktop.ColorManager.AlreadyExists:profile id 'hp-Gray..' already exists W [12/Nov/2013:01:27:24 +0100] CreateProfile failed: org.freedesktop.ColorManager.AlreadyExists:profile id 'hp-RGB..' already exists W [12/Nov/2013:10:03:38 +0100] AddProfile failed: org.freedesktop.DBus.Error.UnknownMethod:No such interface `org.freedesktop.ColorManager' on object at path /org/freedesktop/ColorManager/devices/cups_hp W [12/Nov/2013:10:03:38 +0100] AddProfile failed: org.freedesktop.DBus.Error.UnknownMethod:No such interface `org.freedesktop.ColorManager' on object at path /org/freedesktop/ColorManager/devices/cups_hp ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: cups 1.6.2-1ubuntu5 ProcVersionSignature: Ubuntu 3.8.0-33.48-generic 3.8.13.11 Uname: Linux 3.8.0-33-generic x86_64 ApportVersion: 2.9.2-0ubuntu8.5 Architecture: amd64 CupsErrorLog: W [12/Nov/2013:01:27:24 +0100] CreateProfile failed: org.freedesktop.ColorManager.AlreadyExists:profile id 'hp-Gray..' already exists W [12/Nov/2013:01:27:24 +0100] CreateProfile failed: org.freedesktop.ColorManager.AlreadyExists:profile id 'hp-RGB..' already exists W [12/Nov/2013:10:03:38 +0100] AddProfile failed: org.freedesktop.DBus.Error.UnknownMethod:No such interface `org.freedesktop.ColorManager' on object at path /org/freedesktop/ColorManager/devices/cups_hp W [12/Nov/2013:10:03:38 +0100] AddProfile failed: org.freedesktop.DBus.Error.UnknownMethod:No such interface `org.freedesktop.ColorManager' on object at path /org/freedesktop/ColorManager/devices/cups_hp Date: Tue Nov 12 12:12:33 2013 InstallationDate: Installed on 2013-10-11 (31 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) Lpstat: device for hp: hp:/usb/DeskJet_940C?serial=MY17O671S5BH MachineType: Acer Aspire V3-571G MarkForUpload: True Papersize: a4 PpdFiles: hp: HP Deskjet 940c, hpcups 3.13.3 ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.8.0-33-generic root=UUID=5830b30e-69e8-4bb4-8a2b-bc2b43c7414a ro quiet splash vt.handoff=7 SourcePackage: cups UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/15/2012 dmi.bios.vendor: Acer dmi.bios.version: V2.07 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: VA50_HC_CR dmi.board.vendor: Acer dmi.board.version: Type2 - Board Version dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: V2.07 dmi.modalias: dmi:bvnAcer:bvrV2.07:bd10/15/2012:svnAcer:pnAspireV3-571G:pvrV2.07:rvnAcer:rnVA50_HC_CR:rvrType2-BoardVersion:cvnAcer:ct10:cvrV2.07: dmi.product.name: Aspire V3-571G dmi.product.version: V2.07 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1250407/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
