The Canon imagePROGRAF iPF780 36-inch large format printer builds on Canon's award winning line of 5-color printers, and provides enhancements in both hardware, and software capabilities. The iPF780 device is capable of producing an Arch D (24 x 36) print in up to 21 seconds using Economy mode, and an Arch E (33.1 x 46.8) print in up to 41 seconds! The printer has the capability of accommodating 300ml ink tanks, geared towards lowering the cost per print. The included Sub-ink tank system allows for users to use all of the ink in the tank before replacing, while also replacing the empty ink tanks on-the-fly without having to stop a job mid-print and sacrifice print quality.
