The high-speed Designjet Z6200 42" Photo Printer from HP is designed from the ground up to maximize productivity and reduce printing costs. The printer is rated among the fastest in its class and uses extra large 775 ml ink cartridges, significantly reducing the overall cost of ink. The printer contains 4 printheads, each of which hold 2 cartridges so you won't have to switch the matte and photo black cartridges, they're always installed.
The Ethernet port lets you share the printer over a network and an optional print server is available for purchase. The printer's built in spectrophotometer automatically calibrates the printer so you don't have to worry about it or waste ink calibrating.
