1.6.3 External Communications
1.6.3-1 Transmitting print contents
(1) Function
● The received print content will not be reflected in printing immediately, but temporarily held
in buffer.
● To facilitate operation, first input fixed characters that do not need to be changed, and then
transmit only the print items to be changed.
(2) Restriction
● The maximum number of print items which can be sent at 1 time is 8 print items (maximum 80
characters).
● Print content cannot be sent to the item number(s) which does NOT exist.
1.6.3-2 Clearing buffer and restarting printing
(1) Function
● When text "clear buffer" is transmitted, the print contents held in buffer will be cleared.
● To restart printing, perform the following procedure after transmitting text "clear buffer".
If this procedure is not followed, the print contents stored before the buffer cleared may be
printed.
Procedure:①Transmit print contents so that print contents sent at least N times remain in the
buffer.
②Transmit text "restart printing".
③Printing is possible whenever the print start signal is input.

(2) Restriction
● Independently transmit text "clear buffer" or "restart printing": These cannot be transmitted with
another text (print content transmission, print data call-up transmission, etc.).
● Transmit text "clear buffer" or "restart printing" only while printing is not in progress.
● Input the print start signal at least 500 ms after ACK is returned to "restart printing".
1.6.3-3 Print data call-up transmission
(1) When calling up print data via communication, always execute the call-up before transmitting
data to the buffer. If call-up is executed in the Ready status, the called up print content will be
printed.
