networking via printer port?

[subhailc]

i've heard (more than once, now) that it's possible to connect directly to another pc through a printer port/cable - is this true? if so, how?

Sounds like the Direct Cable Connection thing that's been available for years (and mostly ignored because it just isn't that good).
