A laser printer *is* a photocopier. To make a laser printer, a Cannon
photocopier "engine" was combined with a mechanism for converting wire-borne
data into the image. The placement of the image on the paper uses the same
mechanism and the same ink.
On cardstock, laser printers and photocopiers do not produce a permanent image.
The ink is relatively easy to abrade off. Since there is no impact, there is
nothing whatever left on the paper when this happens. It may be water- and
weather-resistant, but it won't stand up to rubbing or scraping.
