Print in the app store just came out tonight. I always thought that it was odd that there were no apps like this in the store, but perhaps this is an actual good side effect of Apple loosening up on which apps are accepted. I'm getting tired of new farting apps. These are actually useful.
I haven't tried it yet. Waiting for a few more reviews. Seems restricted and requires software that must first be installed on the computer.
Being able to print word documents would be great. It would be nice to be able to print to whatever printer was closest to me while on my university's campus. Many times I will email myself documents and print them off at school. This would save a little time and be just plain cool. Apple needs to add this to the email and safari apps with some sort of universal driver. Also, a common file repository would be great.
I also have a Canon printer...and Canon everything else. When reading about this, I kept trying to think of someone I know who has an HP, and all I could come up with was Canon, Lexmark, Kodak, and Epson. I had HP back in the day, but they were crap. Ink heads were always getting clogged and the ink was too pricey.
