Strange behavior of HP-41CV with Math PAC and IR Printer Module

That should disable printing, specifically, clear flag 55 so the calculator will behave as though no printer is present, and flag 21 will cause VIEW and AVIEW to halt program execution.

This should be analogous to PROFF on the HP-42S.

Confirmed !
