HP Officejet 150 vs 100
Besides to print, the most improvement is that the HP Officejet 150 offers copy and scan (up to 600 x 600dpi) capability. It also features 2.36-in (5.9 cm) touchscreen CGD (color graphics) and 1 Memory Card slot (Secure Digital/SD and MultimediaCard/MMC type). But, the printer engine in the Officejet 150 is essentially identical to the Officejet 100 which pretty much guarantees similar performance.
