ABSTRACT:
In a computer and a printer connected through a parallel interface called Centronics interface, after determining whether or not bidirectional transmission of data with the printer is possible, a printer setting device displays a message indicating the status or settings of the printer. An operator selects and sets the desired printer settings while viewing this display. On the other hand, when bidirectional transmission with the printer is not possible, predetermined default settings are set to the printer and the device displays the default settings. Therefore, the printer setting device can operate even when support for bidirectional transmission of data is not provided. Further, regardless of whether bidirectional transmission of data is possible, the operator can freely change the settings of the printer so that the functions of the printer can be more fully utilized.
