Teo, Probably you just needed to Resume (unpause) the printer (right-clicking the printer in system-config-printer and selecting Enabled or Resume printer in the cups webinterface) to make it work again, can you try?
Thanks in advance, Pascal ** Changed in: cups (Ubuntu) Status: Confirmed => Incomplete -- 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: Incomplete 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
