David, I don't think that cash register tape would be robust enough.
Remember that paper tape was robust enough to go through the meatgrinder of
an ASR 33--and for those who had to use a tape over and over again, there
was mylar-coated tape.

You know, paper tape's still very much around in the CNC field.  Here's a
supplier:

There are others.  Admittedly, it's not cheap, but how many thousand feet
are you planning to punch?

Cheers,
Chuck
