I just bought an HP OfficeJet Pro 8740 multifunction printer.  It supports Postscript 3 emulation, according to HP, and their Universal Postscript Driver does work in Windows 7.  Is it possible to extract a .ppd file from the Windows driver installer files that could be imported into the ArcaOS5 Postscript driver?  The printer works with the .ppd file from a Linux CUPS installation, but it doesn't offer the choices of which tray, which paper sizes, etc., that the Universal Postscript Driver does.
