I have a problem with bar codes on labels. I have two Zebra printers ZTC ZM600-200dpi ZPL(unreadable code) and ZTC ZT420-300dpi
. They are connected to the same network, have similar settings. The problem is that one of them prints for long barcodes, which then can not be scanned by a scanner (screen). What may be the problem, I tried to compare the settings. I changed to identical and nothing. How to change barcode size?
