Prevent a zpl file from being printed twice










0















I have a program that generates a text file with zpl code in it. The file is supposed to contain unique barcodes that I only want to be printed once. Is there a way to either guarantee a unique barcode or prevent a file from being printed more than once.

  • When I send my vendor the zpl file to print they are not supposed to reprint that file. In that file I will have a sequence of barcodes from 10000-10100. Since ZPL doesn't store any veriables/ sessions the second time they go to reprint the file it will just reprint the same barcodes.
