Meaning of the signals

When the bidirectional is OFF:

¥nStrobe (Pin No.1)

The synchronous signal for the reading of data 1-8; needs the LOW active pulse.

¥Data1-8 (Pin No.2-9)

For the 8-bit parallel data input, Data 1 is LSB (lowest bit) and Data 8 is MSB (upper- most bit).

¥nAck (Pin No.10)

A LOW active pulse signal which indicates that the received data has been taken in.

¥Busy (Pin No.11)

A HIGH active signal which indicates that the printer is unable to receive data.

¥PError (Pin No.12)

A HIGH active signal which indicates that there is no more paper.

¥Select (Pin No.13)

A HIGH active signal which indicates that it is possible to receive data.

¥nAutoFd (Pin No.14)

The signal when the bidirectional is ON.

¥Chassic Gnd (Pin No.17) Connected to frame ground.

¥Peripheral Logic High (Pin No.18)

+5V voltage on the printer side.

¥Signal Ground (Pin No.19-30) Connected to the various signal ground.

¥nInit (Pin No.31)

The LOW active pulse signal which requests for the initialization of the printer.

¥nFault (Pin No.32)

The LOW active signal which indicates that errors such as paper jams have occurred in the printer.

¥nSelectIn (Pin No.36)

The signal when the bidirectional is ON.

When the bidirectional is ON:

All connections adhere to the IEEE 1284 connector standard.
