It's lengthy but this sequence works to clear out the buffers
everywhere.

Power off the printer
Unplug the parallel port cable
Stop cups (or lpd)
Unload the lpt kernel module (it has a buffer!)
Plug in the parallel port
Power on the printer
Start cups (or lpd) which will reload the lpt module

I have had issues with unloading the lpt module with the cable still
plugged in on some models of Panasonic printers. Even with the power
off, some printers will acknowledge the existence of a device on that
parallel port. That will block the module unload as it does still have
data to send. I have not found a way to flush the module buffer with out
unloading it or re-writing it to add a user-space hook to listen to kill
command.
