AUTOEXEC.BAT Standard Configurations Parallel DOS Commands If the previous check did not produce the desired result, ensure that the AUTOEXEC.BAT file contains the following statements for parallel interface communications: MODE LPT1: , , P For MS-DOS version 4.0 and above: MODE LPT1: , , B Note 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 appropriate printer port. If the problem persists, see Table 7-34, “Communications Checks,” on page 7-82. Serial DOS Commands Most IBM-compatible computers default to a parallel printer port.
To ensure that information is sent to the serial printer port, type the following MS-DOS commands at the MS-DOS prompt, or include them in the AUTOEXEC.BAT file. MODE COM1: 9600, N, 8, 1, P For MS-DOS version 4.0, or above, enter: MODE LPT1: =COM1 MODE COM1: 9600, N, 8, 1, B MODE LPT1: =COM1 Note These examples assume that you are using serial printer port COM1. If you are using COM2 or COM3, replace COM1 with the appropriate printer port. If the problem persists, see Table 7-34, “Communications Checks,” on page 7-82. Troubleshooting the Printing System 7-81
