oh..
you must be thinking of this (although I don't know what made me think of it, given your vague reference..)

Strange new words I relish,
Like nectar or tonic.
I now know my line printer
Is boustrophedonic.

and I also recall that, when this was posted wayback in 2002 (or so), we hashed out that line printers didn't really print boustrophedonically. (they had to reverse the letters in the reversed path so you could actually read them! but still..)
