Installing an Interface Expansion Board

Selecting the Serial Interface

The printer’s standard interface is parallel. When the serial interface board is installed, the printer automatically detects that the computer is using the serial interface.

Verifying Serial Parameter Settings

Next, you must make sure the serial parameter settings are the same between the computer and the printer. The reference manual explains the parameters. Consult your computer and software documentation to determine the settings your computer uses. Then compare these to the printer’s settings in the following table.
