Any hardware device that enables two or more computers to directly share one or more attached printers without using a network. Print sharers include the following:
If more than two computers need to share a printer, the best solution is to connect the computers to a local area network (LAN) and use a print server to set up a shared network printer. The print sharing devices listed previously are intended primarily for non-networked computers that must be directly connected to printers. In a small peer-to-peer networking setting, you can use a machine running Microsoft Windows 95 or Windows 98 that has File and Printer Sharing installed on it to share an attached printer with other workstations. In larger networks, Windows 2000 Server is a better choice.
Don’t use manual switch boxes with laser printers. The switching mechanism can cause voltage spikes that can seriously damage the printer.
