If your Printronix Label Maker displays 'Invalid Data' and doesn't print, it means the printer received data without valid commands, often due to an incorrect emulation or SFCC selection. This message persists until new data is received or the printer is taken offline.
1. If the emulation and SFCC are correct, get additional diagnostic information by selecting an option under the “xxx Diagnostics” menu, found under the Emulations menu.
2. Rerun the job after selecting the desired option to get the additional diagnostic information.
