Its hard to say why your "plain" paper didn't work - material or
technique. I believe laser paper is formulated to fuse tightly with
the toner - it may have less or no coating. Inkjet paper is
formulated with a coating so the ink does not soak in and widen. I
believe that coating is what makes it work for TT.
When I first tried IJ paper, it would pop off the the board while the
toner was liquid and thus give me bad results. By leaving the iron
on and making it cool while in contact with copper made all the
difference. Also, roughing up the copper creates more surface area
for bonding.
The other thing is you need a very hot iron. Definitely linen
setting. I believe I said cotton earlier, I wuz rong.
