Code 93 DC4 DC4 ESC ! n 15 p EM
CODE-93 bar code 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 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.
The complete ASCII standard character set is encoded by means of 47
combinations of 9 bar/space narrow elements arranged into 3 variable width bars
with their adjacent variable width spaces: each of the bars in the supported
combinations can be 1, 2 or 3 modules wide. The START/STOP character has a 4-
module wide bar. CODE-93 directly implements the basic subset shown below:
0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z-
.SPACES $ / + %
($) (%) (/) (+) (as special control characters)
# (as unique START/STOP character)
The other STANDARD-ASCII codes not presented above will be represented by
means of a combination of one control character in the above set followed by a
symbol in the alphabetical set. The HRC string is printed BELOW the symbol
when f field is set to 1, without check digits: ASCII non-printable characters are
represented in the “control code” format (e.g. CR is ^M, where ”control” is
represented as DARK-SQUARE symbol).
