Steve,
FWIW. Here is an idea that is from far left field.
Coat the glass with photoresist, and print your pattern on a transparency in mirror image. Image the photoresist with the printed side of the transparency against the resist. The photo resist works in negative mode, so that when the photoresist is developed, it will be clear where you want your printed characters. Once developed and thoroughly dried, coat the photoresist with white epoxy ink.Wipe the ink off, so that all that remains is in the openings in the photoresist. When the epoxy is cured, strip the photoresist, and you will be left with the pattern you want, deposited on the back of the glass, where it is safe from wear.
This is highly speculative, and probably needs a few tries to see if it even would work.

Sounds interesting.
All I have right now are black mono printers, so I guess I would have to at some point go to the local printer.
Unless you want to try it for me. I probably should wait to hear from the customer , but if I have a price ready and color options,
that would at least be a start.

Yes, there is a white toner, but it is a specialty item. There is a lot more of it available than when it first came out, back when I was doing imprinting. You have to start with the correct make and model of laser printer.
Yet another idea.? Print on transparency film, black.? Use white
transfer film (use for color overlays on a laser printed piece of
paper) to transfer everything to white.? You can get gold, silver,
etc.? It's the same thing that Pulsar uses for silk screen lettering.
It has to be imprinted over the laser toner, so all of this is exposed
to wear, and has to be protected by either a spray coating or behind
something.

Or they make CMYKW laser printers, now.
Kind of expensive for a one-of project.
Have you thought about having a sign shop cut it out in white vinyl? I've successfully cut and applied some pretty thin stuff. Mirror cut and put on the inside, of course.
Or you could have it reverse cut, stick to the glass, sand blast it a bit to give it a bit of tooth, spray paint in white, then peel the vinyl mask off.
I have a vinyl cutter and sandblaster, so that is how I do this.
