It does work, at least with certain printers and certain inks. And it can
also be used to print solder mask and silkscreen layers (in color, of
course). For extra thin copper clad material, you can use an unmodified
printer, or hack the printer to allow a straight feed path for standard
thickness boards.

See:

details.

I would love to hear if you are able to get the standard HP inks to resist.
So far, MISPRO ink and a curing process have been required.
