Pin #
J5-2 Strobe* – Output used to strobe data into the printer. I/O pin in ECP/
EPP mode.
J5-4 Auto Feed – This is a Request signal sent to the printer to
automatically feed one line after each line is printed.
J5-6 Parallel Data 0 – These signals (0 to 7) provide the parallel port data to
the printer.
J5-8 Parallel Error – This is a Status output signal from the printer. A Low
State indicates an error condition on the printer.
J5-10 Parallel Data 1 – Refer to PD0, pin 3, for more information.
J5-12 Parallel Initialize – This signal used to Initialize printer. Output in
standard mode, I/O in ECP/EPP mode.
J5-14 Parallel Data 2 – Refer to PD0, pin 3, for more information.
J5-16 Parallel Select In – This signal used to select the printer. I/O pin in
ECP/EPP mode.
J5-18 Parallel Data 3 – Refer to PD0, pin 3, for more information.
J5-20 Ground
J5-22 Parallel Data 4 – Refer to PD0, pin 3, for more information.
J5-24 Ground
J5-26 Parallel Data 5 – Refer to PD0, pin 3, for more information.
J5-28 Ground
J5-30 Parallel Data 6 – Refer to PD0, pin 3, for more information.
J5-32 Ground
J5-34 Parallel Data 7 – Refer to PD0, pin 3, for more information.
J5-36 Ground
J5-38 Parallel 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.
J5-40 Ground
