The format of the Master Select code is shown below:
ASCII:
Decimal:
Hexadecimal:
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.

For example, if you want to print a title using double-wide 12 cpi
characters in double-strike mode, you would add these three decimal
numbers together to calculate the value of n:
