I phoned the printer.   The woman at the print shop said that yes,
they could print in white toner using the color laser printer onto a
nonwhite paper.    However, I have not yet tried it.   I was thinking
of just using the same transfer paper that I use for the Cu board
trace artwork.     I may decide to buy some of the white TRF paper
instead, or use black toner if the fiberglass is light enough.
