A different Peter but I'll chip in anyway :)

I think he just placed the PCB over the guide he'd printed in the previous
pass.  Some printers that can be used with this technique allow printing
directly on CDs (usually with some sort of cradle), so you can just stuff
your PCB into that rather than doing any mods; that guy may have modified
his though, I don't know.

I've seen this technique done by pre-etching the PCB (couple of seconds in
FeCl) to rough up the PCB so the ink adheres, but that guy just roughed it
up with sandpaper, which seems much better (less mess).  Might be worth a
try sometime; seems much quicker/less elbow grease than toner transfer.
