In addition to earlier:
You could try the parport driver. For details,
see the files /usr/src/linux/Documentation/parport*.txt
in the kernel sources, assuming the standard location
for the sources.
The advantage with the driver is that the parallel
port may be shared between the printer and the other
thing (JTAG).
