I had a client with an HP P1102w Printer today that I needed to get on the wireless network so they could print from their laptop.
The driver that I downloaded from HP did not help me install it wirelessly. It was supposed to but there was something called the HP Firmware downloader that opened on the dock with the default application icon and then did nothing.
This video helped me make it happen after that. Essentially you need to be plugged in via USB and then do what they do in this video. This will help you get it on the wireless network for good.
Otherwise, this seems like a fine LaserJet printer. HP seems to be asleep at the wheel when it comes to the Mac drivers though. No pun intended.
