and is 14-digit fixed length. Valid ASCII code is 48-57. Standard ratio

Bar code M: UPC 2DIG ADD

This is a supplementary code of 2 digits for UPC and consists of only

numeric characters and is 3-digit fixed length. The 2-digit numerics are

input from the computer or applications software and the 3rd digit is a

numeric is sent from the computer, the printer compares the

characters with the calculated checksum. If they do not agree, the

printer prints all bar codes 0 (zero).
