The format of the Master Select code is shown below:

ASCII:ESC ! n

Decimal:27 33 n

Hexadecimal: 1B 21 n

To send the Master Select codes to your printer in a decimal format, for example, you send the codes 27, 33, and then whatever value you choose for the variable n.

The variable n is a number that identifies the typestyle or combination of typestyles. To find the value of n, look at the Master Select table below and add up either the decimal or hexadecimal numbers for the features you want.
