Hi there Listers, Pep: I guess this issue is (somehow) printer driver related. I have exactly the same model and also a 450Mhz PM G4 Cube and AFAIR I was 'forced' to reinstall/update HP's printer driver after any OS X 10.2 (aka Jaguar) upgrade. Please check here for the latest driver(s): < http://www.versiontracker.com/dyn/moreinfo/macosx/12507 > (I'm not able to check right now but) I guess I'm still running v2.3.1 with Panther and issues vanished since then. Good luck, LM >>> pep27 at mac.com - 2004/02/25 22:42 PM >>> I have a G4 450 Cube w/448MB RAM running OS X.ii.viii, and I'm trying to print via USB on an HP DeskJet 1220C... The printer appears in the dropdown list, but when I attempt to print, Print Center spontaneously cancels the print job... I tried deleting and re-adding the printer w/o luck [This worked for me previously under OS X.i.v]... As a test, I hooked up my little travel printer, a Canon BJC 85, and it works just fine... Strangely, the Deskjet prints test pages without issue... Any idea how I should proceed troubleshooting?... Anyone else ever run into this problem?... I doesn't matter whether I try to print a .doc, .pdf, or whatever: Same result every time... Pep
