If you’re an impatient type like me, you’ll be frustrated by the slowness of almost all laser printers.
Today’s invention offers a way to speed things up.
Small areas of the image to be printed would each be written onto a flat, charged plate by dedicated, local lasers.
A bank of such plates would allow both sides of many pages to be printed at the same time.
This would parallelise the process so that the overall print time for a multipage document could be reduced to milliseconds (at the expense of hugely duplicated hardware).
