The HP PhotoSmart 8150 Inkjet Printer offers color resolution up to 4,800 x 1,200 optimized dpi color, and 1,200 x 1,200 dpi black. It prints up to 20 pages per minute in both black and color, and can print borderless 4 x 6 photos as fast as 27 seconds. Users report good looking photo prints, but the printer stops recognizing the color cartridge after a year.
