boustrophedonic

    (From the Greek "boustrophe-don": turning like oxen
   in plowing; from "bous": ox, cow; "strephein": to turn) An
   ancient method of writing using alternate left-to-right and
   right-to-left lines.  It used for an optimisation performed by
   some computer typesetting software and moving-head printers to
   reduce physical movement of the print head.  The adverbial
   form "boustrophedonically" is also found.
