Your problem can also be a hardware defect on the computer side. Did you test the printer(s) on other computers running Ubuntu? Do you also have problems with other USB devices? If your computer dual-boots to Windows, does the problem occur there, too?
As a workaround, you can at least make the printing (not the scanning and/or fax) functionality working by using the printer as a network printer. If it does not have a network interface, connect it to the USB port of your router or NAS and then it should appear as a network printer with the IP/host name of your router or NAS (in some cases you need to activate print server functionality via the web interface of your router or NAS). Does this work for you? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1398595 Title: Working printer device communication error (5012) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1398595/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
