BcsSEMI is a traditional true type font. Its character set is shown below
SEMI-Single and SEMI-Single-Simple are single density dot matrix fonts. Their character sets are shown below
SEMI-Double and Semi-Double-Simple are double density dot matrix fonts. Their character sets are shown below
If you download Barcodesoft SEMI font demo and install on your computer, you will find a Windows application SEMIChecksum. This application is useful when you need to calculate a checksum for either the SEMI M12 or the SEMI M13 standard.
To use it, execute the following command in your shell prompt:
SEMIChecksum -s m12|m13 -t SEMI-string
Remember, the M12 standard needs a 10-character string, and the M13 standard requires a 16-character string.
Some characters in the demo SEMI font have "Demo" watermarks.
