Does your printer have a duplex unit or are you using some kind of manual duplex mode (print the odd pages, then the paper gets put back into the input tray and the even pages get printed)?
Can your follow the instructions of the sections "CUPS error_log", "Capturing print job data", and "Getting the data which would go to the printer" on https://wiki.ubuntu.com/DebuggingPrintingProblems. Can you also attach the file(s) which you tried to print? Please do this for all situations with problems (LibreOffice, evince, ...). Do not pack the obtained file together and do not compress them. Please attach them one by one. This will make it easier for the readers of this bug report to handle them. ** Changed in: cups (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1390994 Title: Lost ability to print duplex To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1390994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
