Trying to configure your HP products like printer and/or scanner on opensuse (or for that matter any linux distro)?
Make sure that you have hplib package installed.
My HP Deskjet 3745 used to work on Mandriva lappie but not on openSUSE PC. After beating around the bush with CUPS, I figured out that there should be some driver in repos. A quick search and tada .. hplib.
Just installed it, reconfigured the printer and wolah its printing. 🙂
