Maybe i am paranoid but I have a case against the Norwegian government. I would like to use my HP printer color laserjet MFP M477fdw against Acrobat that i am renting. That is not working thru an usb-cable.. Probably other instances too that usb is better.... When I try I get you have not internwt. It is files I do not want out on the internet but at the same time it would be better for med to make it digital than having the case on paper.
