Summary: I have had this printer for less than a year for my office and have a light print load. Even on draft quality printing, I'm on my second toner cartridge. The first was the one that came with the printer and lasted about a month. I bought the second cartridge for about $140 and now it has run out. I bought the printer because it got great reviews and it was about 2/3 the price of the comparable HP laser printer.
Summary: I purchased this printer primarily for my personal business correspondence. I fed envelopes (#10) as indicated by the manual and the page setup icon, but they printed as a regular page (that is, the print orientation was vertical on the printed envelope) and only the return address appeared. I dreadfully contacted customer support. Response was relatively prompt, but it took two emails, when all needed information was in my first email.
