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

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).
