As one who has spent a LOT of time experimenting with direct laser
printing, I can tell you it is not as simple as it sounds. Some laser
printers work very well, others do not. The simplest way to do what
you are proposing is to print on .005 or .007 thick pcb material
(available on ebay), which is flexible enough to go through most
lasers, then glue it on a piece of fr4. Do each side on a different
sheet, etch then glue to make a ds board.
