	I think you need to go to the chooser and disable whatever printer you are
	using.  I have the same problem when using both ports for midi channels,
	so what I do is always disable the printer first, and it then works ok.
	Since it is so irritating to remember to do it, I've set up macros to
	enable the printer again, and to disable it.
