This active low output selects the printer. This
is the complement of bit 3 of the Printer
Control Register.
Refer to Parallel Port description for use of this
pin in ECP and EPP mode.
This output is bit 2 of the printer control
register. This is used to initiate the printer
when low.
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.

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.
