parport_pc 7636 1
parport   7344 1 [lp parport_pc]
and a last line with the name of your network card driver

Ctrl-C to stop the pings.

Type ping  www.godaddy.com and you should see some ping replies.
Ctrl-C to stop the pings.

If the printing of the letters on the printer look fuzzy, use a shorter parallel printer cable and try again.


On some strange motherboards, the built-in LPT1 port becomes disabled if you boot up without
a monitor attached.
Boot up with a monitor attached, after boot up, type ps ax and you should see a line like this
/usr/sbin/p9100d
Boot up again without attaching the monitor, after boot up, attach a monitor and type
ps ax and you should see /usr/sbin/p9100d , if it disappears, you have one of those strange motherboards.
There is no cure. g You need to either change motherboard, or add an ISA add-on multi-function IO card
with a parallel port, or leave an old monitor attached permanently.
