Now, as I expected, no black with her printer. This seems to confirm
my printhead needs to be replaced.

I then put her "good" printhead back in and just for grins, run a
printing test. NOW HER PRINTER WON'T PRINT BLACK. It's as if my
printhead "infected" her printer.

I would suspect that your initially no black printhead had developed
a short circuit, and this blew the control board.
You take the short circuit printhead over to your daughters, it blows
her control board.
Now you have two dead control boards that new heads won't fix.

I've met this many times, processors and other very expensive
devices make incredibly fast and expensive fuses, in fact
the fastest fuses around with 775 legs.

What you should have done, with hindsight, is get a new
head and put it in your daughters working printer, and being new,
it should have worked fine. Then put her used head in your
no black printer, and if no black, it would cpnfirm your printer
is now a doorstop.
