port is set for bidirectional operation (ECP mode) ; see
“Configuring integrated peripherals” in Chapter 2 for more
information. If you use ECP mode, check your parallel device

setting; then set jumpers JPS and JP18 to match the setting, if
necessary. See “Changing the Jumper Settings” in Chapter 4 for
more information.

selected the correct printer within your software application.
