I tried to get this printer work, but no luck yet. On
openprinting a user reports that KX-P7105 is perfectly compatible with the HP LaserJet 5100 driver. Please note that KX-P7100 and KX-P7105 are quite different, at least on the resolution side (
specifications). Here I cannot get KX-P7100 working this way. Most similar driver would be "HP LaserJet 1100 Foomatic/ljet4 (recommended)", but it doesn't make it work (not through samba, at least).
