In setting up my HP LJ 4100 I have used 2 devices. Earlier: HP Laserjet 4100 Series v.3010.107 Postscript (recommended) (EN) Current: HP LaserJet 4100 Foomatic/hpijs, hpijs 2.8.2.10 - HPLIP 2.8.2 Now I am setting up a new Kubuntu computer. Can anyone comment on which device would be the best to use? Larry
