If you have two computers and only one printer with a USB port, you can share the printer between the computers with a fast connection. No software or special modifications are required, although both computers will need to be loaded with the drivers for operating your particular printer. The drivers can be found on the software discs that came with the printer. To make the connections, you just need to get a USB hub available at computer stores and electronics shops, then follow some steps.
