The same bar code printed in the opposite direction would be as follows:
"<RL><RC200,70><X2><uL5>J1234K5678L"
5.14.42 I 2 OF 5 SUPPLEMENT
Interleaved 2 of 5 bar code is a numeric only bar code. All I 2 of 5 bar codes must contain
an even number of characters and are bracketed by a stop and start character. The
character is the colon (:). The letter F is used to select interleaved two of five bar code.
Note: this bar code can be printed in either a 2:1 or 3:1 wide to narrow ratio. The following
are 2:1 ratio commands (the default value).
A typical picket fence bar code would be sent as follows:
"<RC0,10><X2><FP3>:123456:"
The above prints a 3 unit high (24 dots) bar code starting at row 0 column 10. The bar code
will extend down and to the right from the initial row and column position.
A typical ladder orientation bar code with interpretation and a default width of 4 would be
sent as follows.
"<RC0,70><FL>:123456:"
An expanded (doubled) version of the above bar code would be as follows:
"<RC0,70><FL><X2>:123456:"
A 3:1 ratio of the above expanded (doubled) version would be as follows:
"<RC0,70><FXL><X2>:123456:"
5.14.43 EAN13 SUPPLEMENT
EAN13 is a numeric only bar code. All EAN13 codes must contain a variable parity bit
followed by a front guard character (J), 6 left-hand characters, a center pattern (K), 6 right-
hand characters and an ending guard pattern (L). The parity of the left-hand characters is
determined by the first (parity) bit. The last bit in the right-hand side is the check-digit. The
firmware automatically recalculates this value after transmission. The letter E is used to
select EAN13 bar code.
A typical EAN13 ladder bar code sequence would look like the following:
"<RC0,70><EL5><BI>9J014561K780128L"
The above command line would generate a 5 unit wide bar code starting on row 0 ,column
70. The BI command causes the interpretation to be printed with the bar code.
A typical expanded EAN13 picket fence bar code with no interpretation would be as follows:
"<RC0,10><X2><EP3>9J014561K780128L"
5.14.44 CODE 39 SUPPLEMENT
Code 39 is an alphanumeric bar code. All code 39 data must be bracketed by an asterisk
(*) on both sides. The letter N is used to select the three of nine bar code. Note: this bar
code can be printed in either a 2:1 or 3:1 wide to narrow ratio. The following are 2:1 ratio
commands (the default value).
