Bar code C: UPC-E

This bar code consists of only numeric characters and is 8-digit fixed

length. The first digit numbering system character is "0" fixed so it is

not transmitted. The 6th or 7th digit numeric excluding numbering

system character is sent by the computer or applications software.

(Transmit UPC-A shortening code.) The printer automatically

calculates the checksum at the end of digit (8th). When the computer

transmits the 8th digit numeric, the printer compares the characters

with the calculated checksum. If they do not agree, the printer prints

all bar codes 0. If supplementary code is to be added, refer to item of

bar code M and N. Element size is 1 : 1, 2 : 2, 3 : 3, 4 : 4, 6 : 6, and 8 :

Bar code D: Interleaved 2 of 5

This bar code consists of only numeric characters and even digits are

variable in length. When an odd digit code is transmitted, the printer

automatically adds one digit with 0 to the top of the transmission code

to convert the number of digits to an even number. Valid ASCII code is

48-57. Standard ratio (ratio of thick bar to thin bar) is 5 : 2.
