Zusammenfassung:	PURPOSE:To improve the operating efficiency of a printer switch device by providing a selection circuit which selects one of plural printers together with a switch and a buffer circuit and actuating plural printers selectively to a single word processor. CONSTITUTION:A printer of printers 3(1)-3(n) selected by a printer selection switch 43 provided to a printer switch device 4 is connected to a word processor main body 1 via the device 4. The document produced by the main body 1 is printed by a connected printer with a print start indication given from a keyboard 2. The switch 43 contains the switch groups in the same number as printer connectors 42(1)-42(n), and the contact information on the switch 43 is sent to a switch control circuit 44. The control output of the circuit 44 is connected to a demultiplexer 45 and a multiplexer 46. Then a desired input/output group is selected.
