Parallel printers also use those devices, though (even though cups
usually talks through the lp module to them, through /dev/lpN). So far
we didn't give users access to printer devices, mostly because
cups should be the only thing which talks to them, to (1) avoid access
conflicts, and (2) avoid tampering printers and other users' print
jobs.

I'd really like to avoid it for printers, see above.
