I'm also experiencing these problems. But in my case i am able to print text from gedit and print HTML (including images) from Firefox. I cannot however print from Inkskape or print a PDF from Evince. I've updated to cups 1.5.3 and installed the latest version of HPLIP. Model HP CP1515n and worked flawlessly in the previous 11.10 release.
For your information ipp is not directly listed as an option in the list when i try to install one of these printers. I can choose between HPLIP and Appsocket/HP jetdirect. ** Attachment added: "CUPS error_log" https://bugs.launchpad.net/ubuntu/+source/cups/+bug/973270/+attachment/3222675/+files/cups_error_log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/973270 Title: Printer does not provide REQUIRED job history.
