DATAO to 7
These signal lines transfer data to be read by the printer.
Data 0 is the least significant bit (LSB), and data 1 is the
most significant bit (MSB).
*ESTB
This pulse is normally at a high level. The printer reads
data while this line is LOW.
*EINIT
This signal is normally at a high level. When it goes to
low level, the printer is reset to its initial state, and
the printer buffer is cleared.
*ESLCT IN
When this Signal is at a low level, the printer is possible
to entry the data. But, this signal is fixed to low level
by the printer.
*EAUTOFD XT
When this signal is at a low level, paper is automatically
fed one line at a time after printing. This signal level
can be fixed to a low level with a setting of the printer.
