The needed modules are loaded.

No sign of the parport (or lp) module being loaded when booting. ppdev
depends on parport so this is worrying.

The lp module also depends on parport. It looks like CUPS is a getting
parport loaded.

No devices created. This doesn't happen on my up-to-date Wheezy machine
with a stock kernel; have you got the same setup?
There are BIOS settings for the parallel port; you could see whether
altering them makes any difference. The cable and its connections might
also be worth looking at.
