Bar Code B
Identifies the UPC-A bar code. Numeric-only bar code with a fixed length of 12
characters. Eleven digits supplied by host or application software, 12th digit checksum
supplied by printer. If the 12th digit is sent by the host, the printer will check that
character against the calculated checksum and will print the bar code as all zeros if they
do not match. Addendum codes for this font are described by fonts M and N. The
normal ratios that the printer can print are 1:1, 2:2, 3:3, 4:4, 6:6, and 8:8. These ratios
actually specify size of elements since UPC type bar codes are element based and not
ratio based. (Maximum 10 bar codes per label.)
