Abstract: Disclosed herein is a printer system. When a user presses a button, a button unit generates and outputs a key value corresponding to the button. A printer is directly connected to the button unit, and generates and outputs command data designated for the key value input from the button unit. A host computer receives the command data generated by the printer and sends the command data to one of target computers.
