● The IJ printer executes an internal process to make printing preparations in accordance with
the received print data. Do not enter the print start signal during internal process execution.
● In the overwrite-protected mode, initiate the next communication after completion of
printing.
● In the overwrite-enabled mode, the next communication can be transmitted during printing,
but the ACK/NAK response does not return until the ongoing printing
operation is complete. (t=async.)
● When a print start signal is input with shorter timing than T2, the fault "Print data
changeover in progress M" occurs.
*3 If the communication time interval is not sufficiently secured, it may not operate normally.
*4 When there is a data matrix setting, the time is as follows:
