CODABAR
DC4 DC4 ESC! n 22 p EM
The Codabar bar code data fields do not have a
defined format length and contain data belonging to
the character set listed hereafter:
0 1 2 3 4 5 6 7 8 9 - $: /. +
A B C D E N T * a b c d e n t (only as START/STOP
characters)
The printer allows any combination of
START/STOP characters. If the first and last
characters of the received string do not belong to
the START/STOP characters subset, question
marks will be printed in place of HRC string, if
possible.
CODE 128
DC4 DC4 ESC ! n 23 p EM
The CODE-128 bar code data fields do not have a
defined format length and contain data belonging to
the standard ASCII character set, including control
codes.
Since GS and EM control codes used within the
Compuprint DC4 DC4 ESC (...EM ”Print Bar Code”
control sequence are part of the supported character
set, the host application must SET THE HIGHER-
ORDER BIT of the above control codes to allow the
printer distinguish between encodable data and
string terminators.
