Hi, My friend just started his business. There are 5 people working here including both of us. He bought a Samsung 2165W. He wants all of us to use this printer. What do we have to do? None of the PC's are on a domain. The printer has no ethernet jack. Do we just have to buy a router? Can we print via the ip address of the printer. We are using Vista. We installed the CD. We tried to install via USB. They wanted some numbers. We tried via WPS but we couldnt since there is no router.
