What's a good printer I can buy for Professional Use?

If you want to do this professionally you should have a good color laser and a good inkjet. Inkjets are best for photos and lasers are best for text and (not photo) graphics. Lasers are also cheaper per page and can print a lot faster than inkjets. We have 5 Samsung CLP-300 color lasers in our extended family. They are small, fast and sharp. A set of 4 toner cartridges is $50 at http://www.ccs-digital.com So far we have only replaced one black toner after a year of use, so they do last for 2,000 pages or so. If you're looking for a reliable all-in-one inkjet with good quality output, a solid warranty and inexpensive ink, look at the Epson workforce, NX or Artisan series. The best warranty in the industry. For a year, Epson will fedex a replacement and pick up the old one should you need it. You might find the best value direct from epson.com They had the workforce 500 for $60. It is a copier/scanner/printer/fax with auto sheet feeder. I bought one myself. Great machine. The Artisan is the higher end. Recently Epson has the Artisan 800 on sale for $150 after $150 instant rebate. The Stylus Color 1400 can printer to 19 x 13 inches. You can get 11 free cartridges every month which each hold about triple the ink of Epson cartridges. This does not involve joining a club or mail-in rebates or committing to any other offer.
