Print End (PREND) Signal

•	Rise or fall time (T1) of Print Done signal is less than 150 ns. You have to consider the time when outputting the signal from the connected devices.

•	When the print start signal and reprint signal are outputted simultaneously, the print start signal is enabled and the product does not perform reprinting.

•	The reprint signal is valid only from the time of the print operation end (QTY=0) until the next print data reception. Other than that, the product does not perform reprinting.
