I'm trying to figure out how to print using HP Photosmart C4580. I've gone to the HP site and they say they only give support to Windows users. One helper on the HP site I got through to assured me it was a supported AirPrint printer, another one said it wasn't. Please help if you can.

Here is a list of supported printers as well as some that are expected to be supported once HP updates their firmware in Dec. Doesn't look like that one is currently supported. That's not to say that they (HP) might not release a firmware update later on or that Apple will release an update to the iOS that will enable air print on more printers - but currently doesn't look like it.
Some users have reported using a method to work around this in order to print to their "non supported" printers on their MAC networks. You can search the air print part of this forum to read about this.
