To be more explicit, you need to find the index in cdevsw of the lp
device.  You will then want to run

	mknod c <index> 0 /dev/lp  # I think that's the right argument order

That is, 'c' for character device, major device is the index in cdevsw,
and minor device indicates which physical one to use. Since you only
have one, it should be 0.

If the above is not correct, someone will correct me, I'm sure. :-)

HTH,

Arnold
