I discovered that in order to enable scan to computer you must have the HP Printer Assistant installed (not Support Assistant tho' this is what directed me to the missing Printer Assistant). I uninstalled and reinstalled the HP Software but for some reason the "full featured package" did not include this crucial programme/app and I spent ages trying to make the computer recognise the printer on the network. Problem solved, now.
