(2) Time interval (T2) between IJ printer response and printing start
● 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.
● The more different items of the print format, the longer the time until ready to print.
*5 If the communication time interval is not sufficiently secured, it may not operate normally.

*7 When there is a QR code setting, T2 Minimum time is 400xN (ms) (N : Number of QR codes).
