It started printing broken lines on UPC labels. We changed the printhead , but it did not help.
We are using thermal transfer with ribbon.
I noticed that ribbon we used before was "WAX 2100" and ribbon we just bought is "WAX 2000" . I switched to old ribbon and it is fine. The problem is we bought 3 boxes of that "WAX 2000".
Anybody know some settings that I can adjust to get good printing with new ribbon?
