Under Microsoft Windows version 3.0, you can install the generic Postscript Printer driver to use your printer's Postscript capabilities. Under Windows version 3.1, you should install a printer driver that has the same name as the specific model name of your printer. If you're unsure which model that is, or are having problems with your driver, install the Apple LaserWriter IINT.
The generic Postscript Printer driver still exists for those applications that require this generic driver name to run properly with Postscript functionality. However, you should only use the generic driver as a last resort. It doesn't perform all operations as well as using the specific model for your printer. Consider the Apple LaserWriter IINT the Generic Postscript driver in Windows 3.1 and above.
With version 3.5 of the generic Postscript driver (shipped with Windows 3.1), any settings required for the print job need to be specified from Control Panel, not from within the application you are printing from.
