After upgrading to hplib-ppds 0.9.6-1ubuntu8 everything was just fine. I reinstalled my printer and during reinstallation the proper driver (hplib/hpijs) was detect automatically.
After the reinstallation, I checked the printer properties and the correct driver was still selected. You can consider this bug fixed. Thankyou. -- My printer driver settings gets reverted to default https://launchpad.net/malone/bugs/39132 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
