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.
