It will go through the [almost] straight optional
paper path of laser
printers and inkjets. (Not the S curves)
I'll bet it will go through a Sanders 12/7 dot matrix printer too. That has a
totallly
straight paper path. Paper in at the top, out at the bottom (strangely...)
However, none of the messages have explained why Will said it is
'extremely difficult to make'. That to me suggests something special
about the card stock.
