I have been using HP Smart until now, and it worked fine. Have uninstalled and reinstalled twice, no luck. Have disconnected printer and waited and reconnected - no luck. It states that the printer is offline - but again, it prints from a document in my computer. Tried to scan from the 7855, instead of HP Smart, and won't - says needs software and drivers; but I just did the uninstall and install and no luck - same response.
