6. Communication
6.1 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.
(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 "printing specifications", "print format", and
"overall column setup" to the IJ printer.
● The IJ printer receives the "printing specifications", "print format", and "overall
column setup" and prepares for making prints under the specified conditions.
(4) User registration 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.
