Another tip for the tape method:
the general method is to print the pattern on plain paper, then tape the PnP on, and print again; this way you can cut the PnP to just barely larger than the pattern and have very little waste. But, that means the first pass is a pretty big waste of toner. When I am doing designs that have a lot of copper area (and thus use a lot of toner) I usually open up the pattern in an image editor and change the color to a very light gray and print that the first time, or quickly draw an empty rectangle the size of the pattern and print that the first time.
