The problem with using MANIO is that I then can't use mass storage at the same time as everything gets sent to the current device.

Is there a way to set the default printer to be via the 82164A without MANIO?

This is a limitation of the HP-41C implementation of HP-IL which is basically designed for automatic operation (AUTOIO).
MANIO will enable you to use the printer commands with the 82164, especially PRP to list programs.
But AUTOIO should be restored for mass storage operations, using MANIO and SELECT can work in principle, but will create problems if you are in trace mode, or are doing DIR.

If you just have to print a few things, a good solution is staying in AUTOIO and not using the printer commands, but SELECTing the 82164 and using OUTA instead of PRA.
