Setting the Interface Parameters
Parallel Interface
The parameters set for the parallel interface match most of the most
common environments and the printer can be used immediately after
the connection to the host.
In case you need to modify the standard parameters see “Printer
Setup” later in this section.
Serial Interface
Because of the great variety of the possible connection configurations,
when you use the serial interface you will need to set the parameters
accordingly.
To assure a correct functioning of the printer connected through the
serial interface, the transmission parameters set for the printer must
match the values set for the host. Check the interface settings on the
host and proceed as follows:
1. Press the
LQ
key while powering the printer on and keep it pressed
until all leds turn briefly on. The printer enters the Setup mode.
2. Insert a blank sheet in A4 or Letter format. The printer loads the
sheet and stops. The
P1, P2
and, if present
P3
and
P4
leds are lit.
3. Press the
PROGRAM
key once. The
P1, P2
and, if present
P3
and
P4
leds are unlit.
4. Press the
LQ
key. The printer prints the first configuration sheet.
5. To change the values of the serial interface parameters, fill in the
marker ( ) beside the value you want to set with a black or blue
ball-point pen or a fiber-pen.
