∗ A LOW logic level on the Logic H signal is as follows:
2.0 V or less when the printer is turned off.
3.0 V or more when the printer is turned on.
The receiver provides an impedance equivalent to 7.5 K ohms to ground.
The BUSY signal is set HIGH before setting either /ERROR LOW or PE HIGH, and held HIGH until these
signals return to an inactive state. The BUSY signal is HIGH:
 During data entry.
 When the input data buffer is full.
 While /INIT signal is at LOW level or during hardware initialization.
 During a printer error condition (See /ERROR signal).
 During test printing.
 When the printer is in default setting mode.
