I like the HP wireless printers but cannot find any significant reviews of the newer models. All the reviews I found were a few years old and the model is no longer available.
I have an HP 2600n at home but it is a color printer and you want monochrome. It has been reliable and is a nice printer, so I look favorably on the HP printers.
I have since added a wireless adapter to the 2600n, so it is now, effectively, a wireless printer. It works well, as long as you are in wireless range.
