Parallel or USB?
If it's parallel just print to LPT1 (or whichever parallel port it's on). You shouldn't need a driver to print in dos to a parallel printer - unless it's one of the "dumb/software" inkjet printers.
Test it by typing "dir >lpt1" at a dos prompt.
A Wordstar driver would provide access to all the fonts and other such settings in your printer.
I've got all the WordPerfect 5.1 (for dos) printer drivers if that helps any.
