	You might wish to look at the various ink jet product marking
systems used to put lot number and date codes on cans, bottles and other
packages.  Almost all of these devices utilize ink jet technology.

	One particular model that I have extensively seen in my travels
is called "Videojet" and is manufactured by A. B. Dick.  "Videojet" will
label containers on a conveyor belt from at least one inch away.  I do
not know what internal pumping mechanism is used for this product, however.
