Homebrew PCBs

okay after doing some reading, it looks like the laser printers 
spray a charge onto the paper and the toner statically attracts to 
the charged spots.  therefore using a copper sheet will redistribute 
the charge.  looks like a laser printer wont work, but i did see 
some people use an inkjet printer directly on copper.
