An alternate term for bidirectional printing, or a computer printer that prints one line from left to right, and the succeeding line from right to left. The term derives from one used to refer to an ancient Greek style of writing in which each line read alternately from left to right and right to left. The word itself comes from the combination of the Greek words bous (meaning "ox") and strophe (meaning "turning"), or, in other words, a style of writing reminiscent of the way an ox plows a field, plowing first one one way, then back the other way.
