Canon's $100 i475D Desktop Photo Printer is one of the least-expensive printers you'll find that has flash-memory slots and a control panel so you can print your pics without a PC.
Quote from the review at PC World:
“Connecting a camera directly to a printer is not new, but until now both the camera and the printer had to be the same brand. The i475D incorporates the PictBridge standard, which allows any PictBridge-compatible camera to connect directly to the printer for instant prints. A number of companies other than Canon make cameras with PictBridge support, including Olympus, Nikon, Konica Minolta, Fuji Photofilm, and Hewlett-Packard.”
