I have an HP DesignJet 70 printer plugged into an USB port in my iMac. When used under OS X it works fine. However, if I need to use it under Parallels with Win XP Pro, the Parallels manual says not to use the native driver found into the disk that comes with the printer. Instead, Parallels support recommends installing the printer using Apple's Bonjour, and that is quite easy. However, when doing so, automatically Bonjour installs the HP ColorJet 4550PS driver, which allows a maximum A4 paper size. The Apple driver also recommended on the manual gives the same result. Installing the HP ColorJet 8500PS driver goes a little bit further - I may print up to A3. However, my printer is an A2 machine, and I cannot find any postscript driver that goes up to that paper size. Has anyone a solution to this problem? Thanks a lot for any help. Robert
