I bought an HP photosmart 5510 at Best Buy for $69.95. Interestingly enough, this is the same price that amazon and newegg has. I can usually get better prices online. Anyway, it is a good buy and a good printer.
I don't print much, but it is annoying to have to go to a local Kinko's to print something, or to have to wait until I am at work to print something. My goal was to spend under $100.00 for a wifi printer that will work from my Ipad and my pc. I checked out iOS: AirPrint 101 for a list of official air print supported printers and printed out a list. The Best Buy salesman was nice, not trying to talk me into a higher end photo printing model, after I told him my basic needs, and we agreed on the 5510, after I told him my preference for H.P.
It took less than 10 minutes to set up after unboxing. I plugged it in and followed the prompts to install the cartridges, print out and then scan a test sheet. I then set up wifi, connecting to my secure network. My Ipad 2 (IOS 5.01) was instantly able to find it within apps, and I sent a few test print jobs. I then downloaded the basic windows 7 drivers from hp.com and set it up as an ip printer. My pc can print to it. I could have set it up with the supplied DVD, but these sometimes install unwanted utilities and software.
I don't need color much, but it is a color printer, and it has a convenient wrap around paper feeder system, eliminating the need for an space taking tray.
I recommend this model, for basic printing needs from an Ipad and a PC.
