Rotate and Print Barcode
In this example, the printer is in Graphic mode and prints a rotated barcode.
Rotation of a barcode is possible only with the printer in graphic mode.
The program performs the following steps:
...
1. Sets the Full ASCII and Check Digit Mod43 symbology options.
2. Opens the connection to the printer.
3. Selects the Human Readable Below, Default Density, and Double Scale barcode settings.
4. Encodes the data, 32123, using ASCII.
5. Obtains the metrics for the barcode.
6. Prints the barcode rotated by 270 degrees.
7. Closes the connection to the printer.
