Public bug reported:
I need to clean my printer heads, and CUPS can't do it (see bug 428065 and bug
377812), so I'm trying hp-clean, part of the hplip package. The documentation
doesn't say what it expects as a printer or device specifier, so I'm trying
hp-clean -pHP_Deskjet_F4200_series (the name CUPS gave to the printer) and
hp-clean -dusb://HP/Deskjet%20F4200%20series?serial=CN98Q5Z1XF05BR (the URL
shown in the CUPS web interface)
but they both fail in the same way:
$ hp-clean -pHP_Deskjet_F4200_series

If hp-clean requires specific Qt and PyQt 4 packages to run, shouldn't
that be a dependency? Or maybe hp-clean should be in hplip-gui rather
than in hplip, if it won't run in non-GUI mode.
