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
