● 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.
● When the Print format is set to "Individual" or "Overall" and Free layout transmission is made,
a communication error will occur.
*7 If the communication time interval is not sufficiently secured, it may not operate normally.
*8 When there is a data matrix and QR code setting, the time is as follows:
*9 When there is a QR code setting, T2 Minimum time is 400xN (ms) (N : Number of QR codes).
*10 When there is a QR code setting, the time is as follows:
*11 When there is a GS1 DataBar setting, the time is as follows:
