I haven't the latest kernel (2.2.13), but
Make sure the parport_probe module is loaded, /sbin/lsmod
and there might be two kernel configuration settings:
CONFIG_PNP_PARPORT:
Some IEEE-1284 conforming parallel-port devices can identify themselves when requested. Say Y to enable this feature, or M to compile it as a module (parport_probe.o). If in doubt, say N.
CONFIG_PRINTER_READBACK:
If your printer conforms to IEEE 1284, it may be able to provide a status indication when you read from it (for example, with `cat /dev/lp1'). To use this feature, say Y here.
I get:
