To peripheral
device
The parallel port normally runs in the default SPP mode. Provided that suit-
able peripheral devices are present, it can also be operated in EPP (En-
hanced Parallel Port) or ECP (Extended Capabilities Port) mode. The mode
is changed in the BIOS settings.
CAUTION
Functional failures caused by poor screening!
Use only metallic or conductive connector/coupling shells providing
large-area screen contact.
