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.
See FDC Pin definition.
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.
See FDC Pin definition.
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.
See FDC Pin definition.
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.
See FDC Pin definition.
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.
See FDC Pin definition.
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.
See FDC Pin definition.
