Summary: I bought this printer three years ago and have changed all the toners at least twice, so I have done quite a bit of printing with it including 1-sided B&W and color, and 2-sided B&W and color. The reason I bought it was because it was a color laser printer that prints duplex on a secure wireless network. The good: Ease of setup - the instructions are thorough and well illustrated. It's not very complicated to get it operational.
Summary: I have been using the Brother HL-4070 for a few months. It is very easy to operate and does duplex well even though it is slow when in the duplex mode. I have been satisfied with the print quality and the speed at which it prints. This is the best printer I have owned for my home office use with one exception. I'll explain that in as much detail as I can. I rated it two stars because there must be some kind of flaw in the toner cartridges.
