we have an 420t zebra printer, which suddenly started printing labels in a wrong way. Say one wanted to print a first name and a last-name on it, now it prints part only of the last name. The code that i send to the printer has not changed at all. When i try to reinstall the printer, i get a certificate error on windows 10, i have calibrated many times the printer, but other than that, i have no idea what else i should do...

i have also tried my code here, it prints correctly, so i guess it is an issue with my zebra printer setup:
