Running Parallels 6/Windows 7 Pro. I just set up the printer (HP Laserjet 8500 PS) and attempted to create a custom paper size. I went to the control panel, selected the printer, went to printing preferences, the Paper/Quality tab. There are a number of paper sizes listed but no custom option except Postscript Custom Page Size, which doesn't allow any settings to be made. I found a tutorial or two, both of which mention clicking a "Custom" button that does not exist in my control panel. Is there some other way to set up a custom paper size? I'm working on 6 x 9 envelopes. Thanks! - Bob
