The print engines in the c80xx series and c81xx series are similar but not identical. If it says they are not supported and you try to find some work around to "trick " the printer into doing it, it could cause damage to the machine.
The "User Guide" has "Paper and Media - Pre-cut tabs are not supported". Previously the customer had a C8045 and was able to do it without any issues.
Does anyone know a workaround for printing on pre-cut tabs using the C8145?
