The simplest type of command consists of a single character to be sent to
the printer. For instance, to print in condensed mode the code format is:
ASCII 
code: 
SI
Decimal:
15
Hexadecimal: 0F
This code can be sent from a program by sending the code 
15 
directly.
More complex commands consist of two or more character codes. For
example, to print in double-wide mode the code format is the following:
ASCII code:
ESC W n
Decimal:
27 87 
n
Hexadecimal: 
1B 57 
n
In this case can be either 
or 0, to begin or end double-wide printing.
You can use either of the following commands to turn ON double-wide
print from BASIC:
LPRINT 
LPRINT 
 
 1)

or 
for the variable, either
the ASCII codes 
and 
or the ASCII characters 
and 
can be used:
ESC s, ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, ESC w, and
ESC %
For example, in BASIC you can turn on double-high with either of these
statements:
LPRINT 
 “w”; 
 1)
LPRINT
