Each signal is at HIGH level when data is logical 1 and LOW when it is logical 0. About an 11-microsecond pulse. LOW indicates that data has been received and that the printer is ready to accept more data. A HIGH signal indicates that the printer cannot receive data. The signal goes HIGH in the following cases: 1) During data entry (ea. char. time) 2) During printing 3) When off line 4) During printer-error state A HIGH signal indicates that the printer is out of paper.
