Fast and reliable. What else could you want?
Their laser and inkjet printers are quite good and the most reliable available. A client of mine just recently threw away an HP LaserJet Series II (purchased new in 1990) because they were tired of looking at it. I'm still using an HP Color inkjet printer than I've had for 15 years. They're stuff is bulletproof.
Their inkjet and impact printers are also quite good and very reliable. You can spend less by buying something else, but you'll have to replace it sooner, so you won't be saving any money.
Again, you can buy something cheaper, but it won't be as good and it won't last as long.

Lots of companies make this kind of stuff, and I've used products from most of them. NETGEAR equipment is reliable, and their equipment that can (or needs to be) configured doesn't require a PhD to it. Simple, effective and reliable. I have been disappointed with similar products from some pretty big names, so I just steer clear of them.
