Markus Leuthold, does it work for you when you manually modify your /usr/share/hplip/scan.py according to the above diff? I am not a python expert but perhaps you may have to remove the associated pre-compiled files /usr/share/hplip/scan.pyc /usr/share/hplip/scan.pyo (the two should be hardlinked) to ensure your modified /usr/share/hplip/scan.py gets actually used - or this might also happen automatically by python? -- You are receiving this mail because: You are on the CC list for the bug.
