Woo! Welcome Lexmark, to the 21st century.

I think they used up all their Luddism on the Mac OS 9 drivers: that's an OS that's just shy of ten years old, which must be in Ballmer's "rounding error" zone for market share

Lexmark are crap IMHO. I'd never buy another one after my C532 managed only 500 sheets from a new (high capacity) cartridge. Lexmark didn't even bother to reply to my complaint.

This printer is is Energy Star compliant which is good!

Lexmark gives an Energy Star Typical Electricity Consumption (TEC) of 4.69kWh (units) per week. At a typical UK price of 12p per unit this gives an electricity cost of about £29 per year.

As I understand it, for a printer of this speed (35ppm), the TEC is based on printing over 18,000 monochrome pages per month. This is on the high side because Lexmark specifies a recommended page volume of 2500 to 10000 per month. Even if colour printing uses more electricity, consumption should in practice remain below £29. Many many would consider to be negligible when compared with the capital, paper and consumables costs.

I am unable to give cost for plugging it into the mains, because Lexmark do not specify standby power consumption.
