Initialization
There are three ways that 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.
Panel initialization When the PAUSE button is pushed with the
ALT button held down.
These three kinds of initialization have slightly different effects.
Software and panel initialization do not initialize the printer
mechanism or clear the user-defined character set. Also, software
initialization does not clear the data buffer of all text.
