How to not print label after ^XZ


I have a simple label that I can print to a ZE500 without problem : the label is stored in the printer (on flash), to print I recall the label, fill the field and after ^XZ the label is printed.

The printer is connected to a plc that command a reprint of the last label, this work great but I have a little problem : when I print the first label from pc, Zebra print my label and the other one from the reprint command.

My question is : is it possible to "store" the label for reprint without really print ? I need a sort of ^PQ0 command or another one that inhibit the print after the ZE500 receive ^XZ

Thanks in advance for support
