The User Manual describes how to install a SavaPage printer on a Windows workstation. It states:
When asked for a printer driver, choose a PostScript printer driver from the list. Any type/model will do, as long as it generates PostScript spool files. It makes sense to select just a simple type/model, without fancy options.
But can you really take any PostScript driver? Which drivers did you try, which failed and which were successful. Did you do something extra to make it work? Version details about Windows and printer drivers are welcome.
