I downloaded the lastest drivers myself and after installing them I could no longer print at all! Every app I tried would just quit automatically. I still had the 1.3 version of the HP drivers for X and am using them. I looks like those of us who are still using 10.1.5 shouldn't be using these. I think they are meant to be used with Jaguar, despite the fact that the website says otherwise. Also, as to the centering issue from the first post, I have no troble doing so when printing to my 1220c from photoshop in X.1.5.....
