	The man page for lpt mentions that you get an interrupt-less
	driver by adding 128 to the minor number, but fails to mention
	that you can avoid the device init by adding 64 and get auto-LF
	by adding 32.
	I needed to avoid the init for my DeskJet 870 so that information
	would have been useful.
	(Luckily there is source code :-)
	BTW, the page talks about "the highest bit of the minor number".
	It may not be obvious which bit this is.
	Compare the man page and the reality.
	Add a few lines to the man page.
