Hi Waters - first, your HP printer does not seem to be on the list of those compatible w/ Apple's AirPrint (
Check HERE); second, check the HP support forums for your printer to see if a 'wireless' printer solution exists?
Finally, for myself - I have an iPad2 & a Canon Pixma printer (not AP compatible); for well over a year I have been using a small program on my desktop computer (nothing needed on the iPad2) called FingerPrint (
Collobos Software) - a new version is available (and more costly than my first version), but has worked great for my hardware combination - good luck!
