Conclusion: The Lexmark P315 takes the idea of printing from cameras and memory cards one step further than most 4- by 6-inch photo printers by not printing from computers at all. It's portable enough to take anywhere, but as it doesn't have a battery, you can use it only where you can plug it in.
Pros: Prints from PictBridge cameras and memory cards. LCD for previewing photos. Highly portable, with a built-in handle.
Cons: Does not print from computers. Photos are tacky immediately after printing. Even after drying, they are easily hurt by water.
