The Photosmart 8750 is an evolution of the current A4 Photosmart 8450, with a wider carriage and some other modifications to cater for larger and thicker papers. It also uses a new No.101 photo cartridge, featuring blue ink, making no less than nine different inks.. Uniquely for an A3 printer, the 8750 is fitted with card slots for direct printing and though there is a mono status LCD, you can’t preview images without printing an index page. Best use PictBridge if not using a connected computer.
