You have at your disposal a unique command that lets you
choose any valid combination of print modes and pitch. This is
the Master Print mode command. It looks like this:
(ESC) “!” n
Here, the value of n defines the print style to be selected. The
value of n can range from 0 to 255, which is the range of values
that can be stored in one eight-bit byte. If you look at each bit in
this byte, you’ll find that each one represents a printing style
variation. Adding the binary values of the selected bits gives the
value of n for a particular combination of print styles.
Table 3-10 shows the decimal values of the bits in the Master
Print byte. To calculate the value n for a particular combination
of printing styles, just add the values of the features that you
want to combine.

Values of mixing print styles for Master Print

1 Elite print 1
2 Proportional print 2

14 1 Emphasized print I 8 I
5 Boldface print 16
6 Expanded print 32

18 I‘ ’ Underline 128 1 For example, if you want to select elite expanded boldface
print, you would calculate the value of n like this:
Elite 1
Boldface 16
Expanded 32
n= 49
The command would look like this:
CHR$(27);“!“;CHR$(49)
