So what's the problem? Just make sure you have SP3 installed, which you should have done ages ago anyway, and find a printer that supports XP. XP Media Center Edition was just XP Home with a few additional programs bundled.
I'm having trouble with my Canon Pixma MP 610 printer and if I can't get it resolved I'll need a new printer. I have a Dell desktop printer with Windows XP Media Center Edition 2005, but new Canon printers appear to require "XPSP3." Can I get a new printer that's compatible with my OS?
