The IEEE standard is only available in paper form and costs money, but the best place to get free info is at http://www.fapo.com/ieee1284.htm For 'the other standard' do you mean EPP? I think this is included in the IEEE1284 spec. For general parallel port stuff, look in the alt.comp.hardware.homebuilt FAQ (ftp://rtfm.mit.edu/pub/usenet-by-hierarchy/alt/comp/hardware/homebuilt/) for lots of links.
