	Hello,

	I've parsed it a bit, and I must say that you're painting the picture darker than it
really is for parallel port scanners. Parallel port scanners listed in SANE do work. No need to
frighten people.

	I'm a bit skeptic about favouring ECP mode. It may be wise for printers, but I think
it is useless for scanners, unless you use some patch that bring DMA reads. From a quick grep
in SANE docs, EPP or ECP/EPP seems to be the recommended setting.
	
	By the way, an EPP scan is way faster than PS/2 or bidirectional mode. Also, I don't
think unidirectional mode is suitable for scanning. 


Regards,
	Stef
