DESCRIPTION
nAutofeed
Output
This output goes low to cause the printer to
automatically feed one line after each line is
printed. The nAUTOFD 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.
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.
This is a status output from the printer, a
high indicating that the printer is not ready
to receive new data. Bit 7 of the Printer
Status Register is the complement of the
BUSY input. Refer to Parallel Port
description for use of this pin in ECP and
EPP mode.
A low active output from the printer
indicating that it has received the data and
is ready to accept new data. Bit 6 of the
Printer Status Register reads the nACK
input. Refer to Parallel Port description for
use of this pin in ECP and EPP mode.
Another status output from the printer, a
high indicating that the printer is out of
paper. Bit 5 of the Printer Status Register
reads the PE input. Refer to Parallel Port
description for use of this pin in ECP and
EPP mode.
This high active output from the printer
indicates that it has power on. Bit 4 of the
Printer Status Register reads the SLCT
input. Refer to Parallel Port description for
use of this pin in ECP and EPP mode.
