It's not possible to autodetect if a printer is attached to the
parallel port without this step.  This is generally harmless, so
it's hard to argue against this behaviour being the default, but
it's certainly true that parallel port use is a rarity for many
people nowadays.

I would suggest blacklisting them in /etc/modprobe.d:

cat <<EOF > /etc/modprobe.d/blacklist-lp
blacklist lp
blacklist ppdev
blacklist parport_pc

and see if this helps.  If not, I would suggest just commenting out
the loading in /etc/init.d/cups.
