The answer is yes, this particular MGA card was the problem.  Another card 
(with different io address of 3BC) printed just fine.  I still have no 
idea how to get lp1 printing but changing the card should fix lp0 in 
linux.  Apparently some older hardware won't work with linux.  Another MGA 
card would do DOS llpro file transfer but not plip.
