Serial Communication
1.1 Overview
The functions described in this document are used to transmit printings and their registration numbers
and enter them into the IJ printer with an external device connected to the IJ printer via an RS-232C
serial communication line. Please connect a USB serial converter to the USB port of the IJ printer and
use RS-232C serial communication via USB serial converter.
(1) Printings transmission
・An "item number" and "character string" are transmitted from the external device to the IJ printer.
・The IJ printer receives the "item number" and "character string" and then makes preparations for
making designated prints.
・The printings of print item for which bar codes or increased-width printings can also be transmitted by
the communication functions.
・When a number (alphabetical character) is transmitted via a communications link to a count setting
digit, the default value can be set.
(2) Print data recall transmission
・A print data "message number" is transmitted from the external device to the IJ Printer.
・The IJ printer recalls print data designated by a "message number" and makes preparations
for making prints.
(3) Print condition transmission
・The external device transmits "print specifications" and "print format" to the IJ printer.
・IJ printer receives the "print specifications" and "print format", and prepares for making prints
under the specified conditions.
(4) Print data registration transmission
・Transmits Print data's "message number" and "message name" from external unit to the IJ printer.
・The IJ printer provides a "message name" and registers data currently being printed as print data of
"registration No."
(5) User pattern character transmission
・This function is used to transmit a user pattern and enter it into the IJ printer.
・A transmitted user pattern can be edited using the "Create user pattern" function, which is
provided as an auxiliary function.
(6) On-line/Off-line transmission procedure
・Specifies switch of online state and offline state from external unit to the IJ printer.
(7) Time control
・Transmits and sets "current time", "calendar time", etc., from external unit to the IJ printer.
・Inquires current time from external unit to the IJ printer and the IJ printer returns "current time".
(8) Remote operation transmission
・Specifies ink ejection/stop, deflection voltage control (on/off) and error reset from external unit
to the IJ printer.
