Summary: I replaced my old HP500 printer/scanner after the ink cartridges were no longer affordable and dried up when I received them. This is a great replacement printer/scanner/copier that does more than the old one and doesn't use those very expensive ink cartridges. The HP Laser Jet 100 MFP M175nw connected to my Dell 745 with Windows 7 operating system with no problem after loading the enclosed software.
Summary: I have recommended at least 3 of these printers in the past year, and personally setup and used 2 of them. The experience of being able to AirPrint crisp bright images, scan photos and documents wireless to an iPad or OS X machine easily makes this workhorse my goto recommendation to SoHo. Xerox just released their AirPrint ready software for their printers, so this might change. But until then, the HP 100 series (175nw specifically) is a great choice.
