PRESCRIBE commands
DUPX (select/deselect DUPleX mode)
Format DUPX mode;
Parameters mode: a number from 0 to 2
The DUPX command instructs the printer to select or deselect duplex printing and
selects the duplex mode. The parameters are as follows.
0=Select simplex mode
1=Select duplex mode, long-edge binding
2=Select duplex mode, short-edge binding
The default duplex mode can be selected by the FRPO N4 command. The
parameter values are the same as the DUPX command above. For example, to
power up the printer with the long-edge duplex binding mode, enter the
command:
ECHO !R! FRPO N4, 1; EXIT; > LPT1
For LPT1, substitute the port to which the computer is connected.
