Get Astrobrite 95 Glossy paper preferably 48# (glossy is much more dense and therefore heavier)

That is an ultra white paper. The main thing is the heat resistance. If you get "printing press" rated glossy stock, it is heat resistant. There fore should work just fine for a laser.

Now using Printing Press glossy stock, the inkjet ink pools into runs and bubbles. Looks horrendous. Inkjet Photo paper absorbs the ink, and has little imperfections in it. When the water based inks touch... those imperfections float-together like a ClearCoat on a car.
