Certainly.  Among all the techniques for home-brew PCBs such as premade photo-
sensitive boards, laser printer resist paper, etc., you can buy copper sheets
without boards for the purpose of feeding them through your printer for 
direct transfer of resist.  Assuming your printer has a reasonable paper path.
Most hp laserjets have an arduous path, and I cannot even feed cardstock 
without jamming, but my Panasonic KX-P4420 is almost straight-through when the
face-up tray is open, and I have no difficulty.  This technique is also fine,
(or at least possible) for multi-layer boards.  For your application, just
don't bother glueing to the fiberglass, glass-epoxy, or whatever.  I get my
copper sheets from MarVac-Dow in Pasadena, but any electronics distributor
should also have them.
