Code 11

DC4 DC4 ESC ! n 14 p EM

The CODE-11 bar code fields do not have a defined format length and contain data belonging to
the character set listed below:

0 1 2 3 4 5 6 7 8 9 -

Otherwise question marks are printed in place of the HRC string, if possible.

This barcode type defines a variable WIDE/NARROW ratio. The bar code is printed at 1/180"
horizontal and vertical graphical printing resolution to ensure high readability rate. Each digit
encoding is separated from the next by a 1/90"—1/60" wide default Intercharacter Gap.

CODE-11 has unique a START/STOP character. The printer generates the couple related to each
symbol. It is visually interpreted by an OPEN TRIANGLE and will always appear on the HRC string
because its size is usually varied to signify the number of check digits being used in the particular
symbol:

v

SMALL open triangle means ONE check-digit

v

LARGE open triangle means TWO check-digit

The f field is meaningless and always defaults to the HRC string print.

Code 93

DC4 DC4 ESC ! n 15 p EM

The 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 the GS and EM control codes are used, the DC4 DC4 ESC (... EM “Print bar-code” control
sequence is part of the supported character set. The host application must SET THE
HIGHER-ORDER BIT of the above control codes to allow the printer to distinguish between
encodable data and string terminators.

The complete ASCII standard character set is encoded using 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 as 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 are 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.
Non-printable ASCII characters are represented in the “control code” format (for example, CR is ^M,
where “control” is represented as DARK-SQUARE symbol).

2 of 5

DC4 DC4 ESC ! n 16 p EM

Bidirectional

The BID-25 bar code data fields do not have a defined format length and contain numeric data only.
Otherwise, question marks are printed in place of the HRC string, if possible. If the o check digit
option field takes a value of 1, an internally generated check digit is added to the encoded string
that will not show on the required HRC string.
