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

 

 

 

 

Each initialization method resets 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.
