Alle,
I have an HP L7780 MFP, which is supported under hplip 1.7.2 but not the current install of 1.6.7. Does anyone know of a way just to add that particular driver to 1.6.7, or will it require removing the standard 1.6.7 and doing a custom install of 1.7.2. If the latter, what would you consider the dangers/other implications of going "rogue"?
It may be possible to lift a newer RPM (probably a SRC RPM) from Fedora Core and then re-building the SRC RPM (man rpmbuild). It is also possible the rpmforge has the newer version of hplip built.
Note: sometimes all that is different for different models of HP MFPs is the model number and/or some configuration settings (typically DPI settings). You might be able to get away with hacking a new config file / ppd file and use an existing driver -- all HP PCL printers are much the same -- newer ones just have more bits...
Best Regards, Camron
