I found a web page on Playstation.com that links to HP's, Canon's, and Epson's list of supported printers:
And my printer, the HP OfficeJet Pro 8600 Plus e-Print All in One, is not listed.
My PS3 cannot find the printer when searching during the PS3 printer setup.
So I'm wondering if it is possible (without using the ePrint service) to somehow use my printer via WiFi with my unmodified stock 40GB PS3 even though it is not supported?
It's no big deal if it can't. Just curious.
