About bar code element type
Any bar code type can be expressed in bar codes by varying bar elements; narrow bar, wide
bar, narrow space, wide space, and intercharacter gap. However, HRI, check digit, and
start/end code have to be added manually. If a specific type of bar code other than
specified earlier does not satisfy your needs, create your own program to translate data to a
specific bar code.
Sample program: Print "CODE39" in code 39 format using bar code element print.
Output:
100 OPEN "LPT1:" AS#1: WIDTH #1,255
110 DC4$=CHR$(&H14):ESC$=CHR$(&H1B)
120 SI$=CHR$(&HF):SO$=CHR$(&HE):ICG=4
