ISO ppm is based on the new international standard for measuring print speed. Black and color print speeds are determined in default, single-side mode, in accordance with ISO/IEC 24734. Black and color two-sided print speeds are determined in two-sided mode, in accordance with ISO/IEC 24734. Actual print times will vary based on system configuration, software, and page complexity. See for details, including complete ISO reports.
Fastest in its class; 50% faster than the competition printing black text in default, single-side mode, or two-sided mode, in accordance with ISO/IEC 24734. Compared to ink jet all-in-ones priced at $199 or less, as of September 2009, based on independent testing.
Get about two times more prints per cartridge compared with Epson's 126 Black ink cartridge.

Yields based on ISO/IEC 24711 in default mode printing continuously. Actual yields will be lower with higher-density images, hot or dusty conditions, less frequent printing, or printing predominantly with one color. All ink colors are used for printing and all-in-one maintenance, and all colors have to be installed for printing. For print quality, part of the ink from the included cartridges is used for printer startup and a variable amount of ink remains in the cartridges after the "replace cartridge" signal. For details, see
Display permanence based on accelerated testing of prints displayed under glass in indoor display conditions; album permanence based on accelerated testing of prints in dark storage conditions. Actual print stability will vary according to media, printed image, display conditions, light intensity, temperature, humidity and atmospheric conditions. Epson does not guarantee the longevity of prints. For maximum print life, display all prints under glass or UV filter or properly store them.
Compared to the best-selling monochrome and color multifunction laser printers available for $499 or less as of January 1, 2009. Actual power savings will vary by product model and usage.
