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).
