The only one of these which is not color is the M1536, which requires the purchase of a "hardware accessory" (Which doesn't seem to be listed anywhere, so I would be leary about buying this thinking I was going to use it wirelessly).
The only one that isn't a multi-function is the CP1525. I already have a multi-function Photosmart, which was about my only choice the last time I replaced my photo printer, because all-in-ones are about all you can get. I've got a stand-alone scanner, so I don't need a printer that scans. And what I am looking for is a printer that just prints black, cheaply. I'll either have to make do with the CP1525, or wait a while longer and see if the technology filters down to something like the P1102w, which is the only single function, black and white laser HP sells anymore.

So... my home printer died - ribbon cable severed from the ink cartridge carriage. Wasn't my favorite printer ever, but it worked - usually. I wasn't planning to replace it, but thougth since I was, I wanted something wireless for my work laptop when I bring it home, and, of course, for the iPad.

I had read that the firmware to allow Airprint to work wasn't going to be updated until December 27th, but the HP info changed and it was available December 9th. I didn't know that - just figured I'd wait until after Christmas - needed a printer now. When I set up the printer on my wireless network, it checked for new firmware and asked if it could download - I let it, and was pleased that the iPad now works with it.

THe 8500a Premium is their top printer in that line - much more robust than the Envy that I also have (office). The 8500a line has individual ink cartridges, and the Premium adds a 2nd paper tray so legal can be loaded in at the same time - or cover stock, or whatever.

I had wanted to get the lower Plus model, but no one had it around me, so I looked online. NewEgg had it for $299 - $200 off list, and it includes extra color cartridges.

The printer is great - no issues at all. The Envy is also nice, but for much lower volume.
