A typical 300dpi laser printer requires about 1Mb of memory to record the
generated bitmap. Higher resolutions, larger pages, color or a combination
of these drive a need for huge memory requirements. "Banding" is used in
PCL-type printers to reduce the need for an entire bitmap: the next band is 
generated on the fly, while the laser-engine strokes the previous band.

Strangely enough, I have never heard of banded PostScript. Why? What are
the technological difficulties in banding a PostScript display-list? Are
there unsolved algorithmic challanges? Why has it never been attempted?
