All printer router connections I've seen turn multifunction printers into printers.
There is some HP printer that is wireless which they do offer network access to the scanner and its other features but in your case, you just turned it into a printer.
I have windows xp and would have uninstalled my hp officejet 7130 all in one printer. Can anyone tell me how to reinstall so I get all functions back such as photo smartcard reader, scanning etc. my netgear router is a MR314 and have a broadband connection
