all-in-one + airport express

i have an hp psc 2355 (regretting it more and more everyday) and i also have a powerbook, and an airport express base station on the way. i was wondering if i will be able to scan and use the card reader function on the printer wirelessly. i wasnt sure whether to post this here or in the wireless/wi-fi section. i read some other websites and threads, but they were all outdated and said it wasnt supported YET.

thanks.
