The following example prints a Code 128 bar code:
<STX>L
D11<CR>
1E000000015010001234567890<CR>
121100000000100Barcode E<CR>
E
F: EAN-13
Valid Characters: 0-9
Length: 13 digits. If the user provides 12 digits, the printer will compute the checksum.
If the user provides the checksum, the printer will check that it matches the expected
checksum. If it does not match, the printer will print all zeros and the expected
checksum. See Appendix O.
Valid bar widths: The fourth character of record is the width of the narrow bar in dots.
All other bars are a ratio of the narrow bar (2 times, 3 times, and 4 times the narrow
bar width).
The following example prints an EAN-13 bar code:
<STX>L
D11<CR>
1F0000000150100012345678901<CR>
121100000000100Barcode F<CR>
