7.2.2 Printer Configuration Setting when Using Serial Interface

When RS-232C Serial Interface is selected for communicating between printer and host, we need to set up
some printer configuration for controlling communication conditions. These configurations can be set in the
ADVANCED MODE LCD menu. Please refer to the Section 3.6 Advanced Mode of this manual to configure
the printer for host computer interfacing.

7.2.3 READY/BUSY Flow Control

Ready/Busy is the hardware flow control method for the serial interface on the GZ4e series printers. By
raising/ lowering the voltage level on Pin 4 of the RS-232C port, the printer notifies the host when it is ready to
receive data. Pin 7 (RTS) and pin 4 (DTR) are the important signals on the printer for this method of flow
control. The host must be capable of supporting this flow control method for it to function properly.
