This class generates ESC/POS printer control commands for compatible printers.
See README.md for a summary of compatible printers and supported commands, and
basic usage.
See example/demo.php for a detailed print-out demonstrating the range of commands
implemented in this project.
Note that some functions have not been implemented:
- Set paper sensors
- Select print colour
