Need advice: writing a char driver

I'd like to write a driver for a small device that is attached on a
bidirectional centronics port. Now I wonder if my driver should work
on top of the lp driver, or use the hardware mutually exclusive. I'd
favour the second approach, because other wise users could try to
print while the device is definitely not capable of printing
anything.
