Digital Prints

Sure, I have a Minotla 35MM Camera, used it for one shooting season(Summer) and put it up on a shelf after I go tmy digital camera. Saved me lots of money on film developing. I also own a very
nice color printer with a photo printing attachement for printing photos. But when I need something bigger that a 4x6 print or more thasn just a few I usually visit a local print shop with a Canon color copier. Anyone do the same thing or suggest a different process? What about the Kodak machines at WalMart?
