Key things to remember:
1. Copper board must be very clean and shiny prior to
ironing.  Use steel wool.
2. Pressure, temperature, and time of heating are all
variables that must be accurately balanced.  You must
experiment.
3. Older laser printers are known to work better
because they use more toner.
4. If you dno't get good results, clean the board and
try again.  A good "print" will result in a a good
etch.
5. You can always fix your mistakes in toner transfer
with a sharpie pen.
