¡
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.
*2 If the communication time interval is not sufficiently secured, it may not operate
normally.
