Use switch 2 on the RS-232 settings switch to select the mode. Switch settings are:
Switch 2 OFF DTR/DSR control
Switch 2 ON XON/XOFF control (must use with a 3-wire interface)
The printer normally ships with switch 2 in the OFF position, which selects

DTR/DSR control.

DTR/DSR control
DSR definition: DSR is an output from the printer. It indicates when the printer is
ready to receive data.
DTR definition: DTR is an input to the printer. It indicates to the printer that the
system is ready to receive data.
