Fanuc PPR - Paper Tape Punch, Printer and Reader : Not quite working

[Eric Moore]

Yep! That is my experience in remote mode, both driven via the panel or
remotely.

You know more than I do, I hope you get it figured out soon! The PPR is
super fun to have on the bench if you have tapes to read or especially if
you have a computer that works with paper tape.
