Hmmm.. Many dot matrix printers (impact and injet) print bidirectionally, 
but I've never come across one (no matter how old) that didn't buffer the 
data intenrally, so the host sent the characters in left-to-right order 
for all line,s and the printer put them on the paper in the appropriate way.

I can imaging a firmware problem in the printer could cause it to print 
some lines backwards (but wouldn't it also print the chracters left-right 
reversed, which is not strictly boustrophedon?), but that's a fault I've 
never seen.
