Both printers share the same engine with 1200dpi resolution and PhotoRET III technology, along with extremely similar body designs. They also both offer CompactFlash Type I and II and Microdrive, SmartMedia, Secure Digital, Multi Media Card, Memory Sticks (Memory Stick Duo, Memory Stick Pro, Magic Gate), and xD-Picture Card compatibility courtesy of slots in the front of the printers.

The difference is simple - the PhotoSmart 245 offers a 1.8-inch color LCD display, where the Photosmart 145 features a 2-line text LCD display. Pricing is set at $149 for the Photosmart 145, and $199 for the Photosmart 245, with availability expected later this month.
