Ethernet Interface

You can use an IEEE 802.3 10BASE-T/100BASE-TX straight-
through shield twisted pair modular cable via RJ45 connector.
Always low.
This signal is set high at the same time that
HostBusy is low in order to request 1284
mode.
This signal is set high to indicate that the
bus direction is from the printer to the
host. This signal is set low to terminate
1284 mode, setting the bus direction from
the host to the printer.
Same as reverse data transfer phase.
Always high. This signal is set low to
terminate ECP mode and return to
compatibility mode.
