Optional Specifications
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.
