		I'm not 100% sure of many things, but here is what 
		is in my KERNEL file related to the printer port:

# Parallel port
device          ppc0    at isa? irq 7
device          ppbus           # Parallel port bus (required)
device          lpt             # Printer
device          plip            # TCP/IP over parallel   
device          ppi             # Parallel port interface device
#device         vpo             # Requires scbus and da


		The ppbus code probably can't tell much about 
		an old DeskJet--that's my hand-waving SWAG;).
		For now, since I believe the DJ works--it works
		with a simple ASCII file, I haven't tried anything
		fancy-- I'm happy.
