automatically compresses data, virtually
doubling the printer memory and
accommodating more complex printing with
available memory.
Energy savings●The printer automatically conserves
electricity by substantially reducing power
consumption when it is not printing.
●As an ENERGY STAR® partner, Hewlett-
Packard Company has determined that this
product meets ENERGY STAR® guidelines
for energy efficiency. ENERGY STAR® is a
U.S. registered service mark of the United
