System Configuration Note MS-DOS System Configuration To communicate properly with the printer, the MS-DOS environment requires the addition or modification of MODE commands in the AUTOEXEC.BAT file. Add or modify the MODE command(s), depending on the interface configuration, as follows: Parallel DOS Commands Most IBM and AT compatible computers default to a parallel printer port. To ensure that information is sent to your parallel printer port, type the following MS-DOS command at your MS-DOS prompt or include it in your AUTOEXEC.BAT file: MODE LPT1:,,B This example assumes that you are using parallel printer port LPT1. If you are using LPT2 or LPT3, replace LPT1 in the example with the printer port that you are using. Since the MODE command is an external MS-DOS command (a program named MODE.COM is run when the MODE command is invoked), the program file must be contained in the root directory, or in a directory specified in a preceding PATH command in the AUTOEXEC.BAT file. After changing the AUTOEXEC.BAT file, reboot the computer to initiate the changes. EN System Configuration 3-37
