Initialization
There are two ways the printer can be initialized (returned to a fixed
set of conditions):
Hardware initialization
When the power is turned on or when
the printer receives an INIT signal
from the parallel interface (pin 31 goes
LOW).
Software initialization
When software sends the ESC @
(initialize the printer) command.
These two kinds of initialization have slightly different effects.
Software initialization does not initialize the printer mechanism or
‘clear the user-defined character set. Also, software initialization
does not clear the data buffer of all text.
