If the printer and host are communicating, a blank page ejects from

the printer. If a blank page does not eject and you typed the file

correctly, see chapter 9, “Troubleshooting.” You may also want to

check your AUTOEXEC.BAT file in DOS to make sure that the

printer’s serial port settings match those of the PC. Look for a

command line like this in your AUTOEXEC.BAT file:

MODE COM1: 9600,N,8,1,P

In this example, the serial port settings are 9600 for baud rate, n

(no) parity, 8 data bits, and 1 stop bit. The p stands for infinite retry.

Now check the start-up page, which prints when you turn on the

printer (unless you disabled it). This tells you the current serial port

settings for the printer. If the serial settings (baud rate, parity, data

bits, and stop bits) shown on the start-up page match those in your

AUTOEXEC.BAT file, you need make no further changes. Go to

the section “Special PC Concerns” later in this chapter.

If the printer’s serial port settings are different from your PC’s, you

must make them match. Refer to the following section, “Changing

Serial Port Settings,” to do this.

Changing Serial Parameters

Since your printer is configured at the factory for the most typical

printing environments, the serial parameters in your

AUTOEXEC.BAT file and on the start-up page should be the same.

However, if they differ, you must configure the printer to use the

serial parameters specified in the AUTOEXEC.BAT file.

Press the control panel keys in the order shown in the following

instructions to change the printer’s serial parameters. The printer

responds by displaying a status message in the message window.
