If I would guess as to what is causing the magenta cast, I would

can only guess that this is why the magenta cast. Next, the magenta
cast document gets sent to the printer driver already converted into
the printer space. Since no color correction is set in the printer
driver , it prints correctly. from what I gather, you can never turn
off ColorSync so apparently it's always doing something and it's real
easy to ColorSync a document twice.. Huh? It's just my guess. . . .

Good guess. In the year 2004 you'd think applications, printer drivers
and OS's could get along well and talk to each other properly but they
don't. OS X is completely ignorant of the fact there are professional
applications in the world that prematch data for output.
If things were smart it would be possible for Photoshop to tag the
print job with the output profile you selected, and it converted the
document with. The OS X could preview the document on-screen correctly.
But today, if Adobe did this, OS X would treat this as an excuse to
further color manage the job when you print as well, which would then
get you less than good quality results. So Adobe doesn't tag the print
job. Your image is converted for your 2200 but is tagged with Generic
RGB (which is what OS X does to untagged data it receives from
applications). Since it's a bogus tag, you get a bogus soft proof.
