Initialization
The printer can be initialized (returned to a fixed set of conditions) in
these ways:
Hardware initialization
∗
The printer is turned on
∗
The printer receives an INIT signal from
the parallel interface: pin 31 goes LOW
Software initialization
∗
Software sends the ESC @ (initialize the
printer) command; the last panel
settings are kept
Control panel initialization
∗
Hold down the Alt button and press
the Pause button (buffer clear); the
last panel settings are kept
All three initialization methods reset the font according to the default
settings selected using the control panel. However, ESC @ does not
initialize the printer mechanism, clear the input data buffer, or clear the
user-defined character set. The control panel initialization does not
initialize the printer mechanism or clear the user-defined character set.
