● Transmission Sequences 6-19
(7) The printings, print specifications, print format, and user pattern data
can be consecutively transmitted in the following order in a single session.
Print format
Print specifications
Printings
The user pattern can be positioned anywhere within the above data chain.
The overall column setup data must be transmitted independently. If an
attempt is made to send it together with the other data, a communication
error (NAK response) occurs.
The print data recall must also be transmitted independently. Even if it is
sent together with the other data, no error occurs. However, the print data
recall takes precedence, rendering the other data invalid.
(8) Up to 1500 bytes of data can be transmitted at a time, including "STX" and
"ETX". If the 1500-byte limit is exceeded, a communication error (NAK
response) occurs.
(9) Any data transmitted by communication (print contents, print specifications,
print format, and user pattern) is not stored except in the following cases.
[Conditions for storing the data]
When the ink is stopped after communication by the Shut down key or
a stop signal.
When switched from another screen to the print description screen by
operating the touch panel.
At 01 minute of every hour.
(10) Communication when "ENQ" is omitted is also possible.
