According to the error_log all is going correctly with CUPS, the filters and the USB communication. The only thing going wrong is that only blank paper comes out.
Can you attach the PPD file of the printer, from /etc/cups/ppd/? Can you look into the front panel menus of the printer whether there is a possibility to let the printer print error pages? If you do not find such a setting you can also look into the web configuration interface of the printer. To access this interface, connect the printer to your network, and enter the IP of the printer in the URL line of your web browser. Print another job and scan the error message on the error page if you get one now. Do you get the test page printed if you print it unfiltered? Run the command cat /usr/share/system-config-printer/testpage-a4.ps | sudo DEVICE_URI=usb://KONICA%20MINOLTA/magicolor%207300 /usr/lib/cups/backend/usb 1 1 1 1 '' Does the test page come out now? Have you also checked whether your paper size is set correctly (A4 or Letter)? The default setting should match with the paper actually in the printer, also the page size setting in the dialogs of the applications should be correct. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879933 Title: magicolor din't work with 11.10 but works in 11.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/879933/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
