After you print the traces and glue the copper to a board, do you then
etch the copper using the toner as resist?  If this is the process,
there is (IMHO) a better way.  You can obtain gel paper which is benign
to the laser printer and transfers toner to copper clad.  I have even
made double sided successfully.   E-mail me if you want more data.
