Selecting typestyles with Master Select
Your printer has a special command called Master Select that allows you to choose many possible combinations of nine printing enhancements. To send Master Select codes to the printer, you must first choose the combination of features you want.
Here are the features you can choose:

The format of the Master Select command is:
