These three kinds of initialization have slightly different effects. In
particular, ESC @ resets
the
typestyle to the current SelecType setting;
the other two methods reset the typestyle according to the default
settings selected by the SelecType settings. Also, ESC @ does not
initialize the printer mechanism, clear
the
input data buffer, or clear the
user-defined character set.
Default Settings
The following table shows the default conditions
that
become valid when
the printer is initialized.
