This printer is built like a tank and will suit a professional studio photographer as well as the serious hobbyist and fine art photographer. The HP B9180 uses four replaceable printheads, each print head handles two colours and can be easily replaced at any time. Boasting eight colours, two of the inks are Photo black and Matte black, these are switched automatically depending on the media type selected. The eight ink cartridges, which each hold 28ml of ink, are stored in a compartment at the front of the printer and remain in the same position at all times. Paper is front loaded via a heavy duty paper tray, this accommodates media sizes from 10 x 15 cm to A3 and envelopes. As with most HP printers the media passes through a U-bend feed system. There is also a straight paper path which is located directly above the paper input tray, this supports media with a thickness of up to 11.5 mil. Prints are delivered onto an extendable output tray.
