Description
STROBE pulse to read data. Pulse width
must be more than 0.5 microseconds at
the receiving terminal.
These
signals
represent
the 1st to 8th bits of parallel data,
respectively. Each signal is at HIGH level
when data is logical 1 and LOW when it
is logical 0.
About an 1 l-microsecond pulse.
LOW indicates that data has been
received and that the printer is ready to
accept more data.
