Initialization

The printer can be initialized (returned to a fixed set of conditions) in

these ways:

Hardware initialization The printer is turned on or

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 control panel

settings are kept

Both 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.
