Lexmark X500n Multifunction Colour Laser Review
This is a multifunction colour laser printer with a low asking price and it could see a lot of application in small offices. It's not that quick, particularly when printing colour, and is quite bulky, but print quality is reasonable, especially when printing text. It's a little bit expensive to print colour on and the five different maintenance intervals could be irritating, especially if your print output is high each month.
