No luck with letting control panel -> hardware and sound -> etc. do it. My printer's not listed. Tried a bunch of them that sounded similar, like the 3050 and the 3250 with the different PCL and PS drivers but none of them worked with my 3150. Grrrrr!!!
No luck finding Series II drivers anywhere. They're not available for download anywhere apparently. Not that I'd necessarily have any better luck with them.
