DESCRIPTION

BUFFER

NAME

A low on this input from the printer indicates

that there is a error condition at the printer.

Bit 3 of the Printer Status register reads the

nERR input. Refer to Parallel Port

description for use of this pin in ECP and

EPP mode.

This output goes low to cause the printer to

automatically feed one line after each line is

printed. The nALF output is the complement

of bit 1 of the Printer Control Register. Refer

to Parallel Port description for use of this pin

in ECP and EPP mode.

Can be configured as an Open-Drain Output.

An active low pulse on this output is used to

strobe the printer data into the printer. The

nSTROBE output is the complement of bit 0

of the Printer Control Register. Refer to

Parallel Port description for use of this pin in

ECP and EPP mode.

Can be configured as an Open-Drain Output.
