I make very small boards so I don't want to run a full page of Toner
Transfer paper.

My technique is simple:

Print the final image on a sheet of regular paper.  

Cut out the image.

Tape a piece of toner transfer paper over the hole, attached at the
leading edge with an address label.

Run the page back through the printer.

My printer has a problem printing on a double thickness of paper,
that's why I cut out the page.  If your printer doesn't have this
problem then just tape a piece of transfer paper over the printed
image made with the test pass.
