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. Default settings The table below shows the default conditions that take effect when the printer is initialized.
