Parallel (LPT) Port Interface

Table 3-3 provides the pin signal descriptions for the parallel port header consisting of 26 pins, 2 rows with

odd/even (1, 14) pin sequence, and 0.079" (2.0mm) pitch.

Note: The shaded area denotes power or ground. The signals marked with * indicate signal inversion.

Signal Descriptions

1 STRB* Strobe – Output used to strobe data into the printer. I/O pin in ECP/EPP mode.

2 AFD* Auto Feed – This is Request signal to the printer to automatically feed one line

after each line is printed.

3 PD0 Parallel Port Data 0 – These signals (0 to 7) provide the parallel port data.

4 ERR* Error – This is a Status output signal from the printer. A Low State indicates an

error condition on the printer.

5 PD1 Parallel Port Data 1 – These signals (0 to 7) provide the parallel port data.

6 INIT* Initialize – This signal is used to Initialize printer. Output in standard mode, I/

O in ECP/EPP mode.

7 PD2 Parallel Port Data 2 – These signals (0 to 7) provide the parallel port data.

8 SLIN* Select In – This signal Output used to select the printer. I/O pin in ECP/EPP

mode.

9 PD3 Parallel Port Data 3 – These signals (0 to 7) provide the parallel port data.

11 PD4 Parallel Port Data 4 – These signals (0 to 7) provide the parallel port data.

13 PD5 Parallel Port Data 5 – These signals (0 to 7) provide the parallel port data.

15 PD6 Parallel Port Data 6 – These signals (0 to 7) provide the parallel port data.

17 PD7 Parallel Port Data 7 – These signals (0 to 7) provide the parallel port data.

19 ACK* Acknowledge – This is a Status output signal from the printer. A Low State

indicates it has received the data and is ready to accept new data.

21 BUSY Busy – This is a Status output signal from the printer.

23 PE Paper End – This is a Status output signal from the printer. A High State

indicates it is out of paper.

25 SLCT Select – This is a Status output signal from the printer. A High State indicates

it is powered on.
