Well my Concise Oxford (1982 ed) says in part: engine: 1. n. mechanical contrivance ... especial as a source of power.... 2. (arch) machine or instrument used in war; instrument, means motor: 1. n. what imparts motion, machine supplying motive power for carriage or vessel, esp internal combustion engine .... It would seem that a motor is an engine that is used to move something. The "print engine" would seem to be based on the archaic definition. This is a common marketing ploy designed to attract people's attention by being a bit different. -- Stuart.Lynne@wimsey.bc.ca {ubc-cs,uunet}!van-bc!sl Vancouver,BC,604-937-7532
