Thanks for the response David. I had tried "modprobe lp", but that gave me the
error:
/lib/modules/2.2.14/misc/lp.o: invalid parameter
parm_io
/lib/modules/2.2.14/misc/lp.o: insmod
/lib/modules/2.2.14/misc/lp.o failed
/lib/modules/2.2.14/misc/lp.o: insmod lp failed

The answer came from Mike Thompson, who had me do
"insmod parport"
"insmod parport_pc"
then "insmod lp"
 (He also suggested I do an "insmod parport_probe" just before the "insmod lp",
but that resulted in a "module not found" type message, and things are working
without it.)

Thanks again!
