personally i'd have a look at the speeddos kernal ... first make a diff 
between the speeddos kernal and the original (so you see the differences, 
somewhere in there must be the centronics code) then trace the kernal chrout 
call to device 6 (i think that was used for centronics in speeddos) and you 
should quickly end up in the routine you are looking for :) shouldnt be 
terribly complex or anything either.
