I have this exact problem. Did someone knows a solution? I have the same problem when printing from a G3 / 266 and a G4 / 466. Mac OS 9.2.2, VW 9.5.2. To two printers, an HP 1220 and an HP 930. They only print in one paper size, letter size in my case. They don't accept legal, tabloid, envelope or other paper sizes.
Thanks,Estuardo Schwank
