HP has a quick and dirty little iPhone (and iPod touch) application that may interest you. It’s free, too!
Anyhow, the application, iPrint Photo [iTunes link], lets you print photos located on your iPhone (and iPod touch) on an HP printer that’s on the same Wi-Fi network. So, you’re walking about your house and say to yourself, “Man, I need to print this photo right now, well, now you can.
Being that I don’t have either an iPhone or iPod touch I can’t test it out; the reviews on the App Store are positive, though.

As silly as the right now statement appears to be, this does make some sense. I rarely sync up my iPhone with my computer, so it would certainly be more convenient than having to upload (or email!) my photos to my computer, and then print.
aahhh now this is one helluve feature eveyrone would love around me :) keep up the good work guys
Just an FYI, this does not work with 2wire routers. If you’re like me and have a 2wire router from ATT, you are out of luck.. :(
