Well, you have 4 options:You can buy an expensive product that lets you convert LPT to Mac Serial/Printer Port and comes with software that supports many printers. (Costs like 50 bucks or so.)
You can use Print2PDF to create PDF files and then print those PDF files on the PC with that printer.
You could get cartridges for your Mac printer....
Or buy a old used Mac printer, I have heard the StylerWriters are buggy printers.
