This high active input 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.
Another status input 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 is a status input 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 input 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.
