Section 6: Using the Printer Interface

The following chart shows the timing in microseconds of these signals.

 

31

INIT*

INIT* from the system resets the printer to its initial power-
on-state. The BUSY line goes high, and any received data is 
printed. When INIT* goes low, the printer resets to the power-
on default state. If data is in the USB buffer, the USB FIFO is 
not reset.

32

ERROR*

The printer sets the ERROR* line low if the printer detects an 
error or out-of-paper condition.
A critical error condition exists when both ERROR* and PE 
are low.

33

GND

Ground level.

34-35

Not used.

36

SELECT IN

The printer does not respond to the DC1/DC3 code when this 
signal, 

 

, is low.

*   Inverted logic (signal is active when low).
