I think the important point for a laser printer is once the paper starts going it can't be stopped. (That's what Brandon meant by being a page printer.) Once the paper starts, you have to feed the image to the printer on time, otherwise you would get gaps. One easy way to do this is to build the page image in memory; then you are assured that the image is available when needed. But you can also create the image in bands, provided the next band is available when needed. Larry Rosenstein, Apple Computer, Inc.
