I use acetone.  It works incredibly well.  

I'd look at the printer that you used.  Do you know the model number?
Is it really toner based and not an inkjet?  Your experience sounds
like what happened when I got an inkjet copy of my artwork mixed up
with the toner based copy (I print on a hi-res inkjet and use a copier
for the toner).  It sort of transfered a faint image.  I suggest you
stick to monochrome laser printers or copiers.  

Keep at it, it is very satisfying the first time you peel off the
paper to find your artwork on copper.
