Maximum power consumption is 35 Watts, and unlike inkjet printers the print won't fade and is water resistant. The cartridges are gel based, not ink, which reduces the chances of clogging. They have pretty fast print speeds and the cost per print is as low as a laser.
Whatever you do, don't bother with refilled inkjet cartridges - I'm a printer tech and I deal with the dramas they create every day.
