^CV
Code Validation
Description: The ^CV command acts as a switch to turn the code validation function
on and off. When this command is turned on, all bar code data will be checked for
the following error conditions:
•
Character not in character set
•
Check digit incorrect
•
Data field too long (too many characters)
•
Data field too short (too few characters)
•
Parameter string contains incorrect data or missing parameter
When invalid data is detected, an error message and code will be printed in reverse
image in place of the bar code. The message will read “INVALID - X” where “X” is
one of the following error codes:
•
C = Character not in character set
•
E = Check digit incorrect
• L = Data field too long
• S = Data field too short
• P = Parameter (occurs only on select bar codes)
Once turned on, the ^CV command will remain active from format to format until
turned off by another ^CV command or the printer is turned off. The command is
not permanently saved.
