Setup a new user in Firefox and verify if the problem persists.

I've just checked out my wife's profile and everything seems to be
working correctly so the issue seems to be with mine.

I did try setting up a new profile but the behaviour is exactly the same,
no choice of printer, just the Epson.

However, I did discover in my frustration, trying everything, that the box
the printer name appears in was editable and when I changed it to the
Dell, lo and behold, I was able to print to it.

Why the FF developers have made it so difficult and non-obvious I cannot
imagine.
