Can't even sign in! My gosh! If I didn't primarily print from a desktop, which was a flawless 0 problem setup, I'd demand my 200 dollars back. It must be bc Hewlett Packard has always been a periphery device for desktops rather then Linux. Damn it's annoying when I have an account and can't even freaking sign the freak in! Damn! ->Btw, if your printer has a interface built into it, then setting up it's WiFi Direct will allow you to share documents to it directly, allowing use w/o the app.<-
