Generally you can print with white ink in many inkjet printers. However, there are some very important notes.

1. Not all printers will work well when this is done. In many cases this is due to the manufacturing of the ink itself. Epson actually makes white ink for some select high-end printers. White will typically be a pigment-based ink rather than a dye-based ink as pigment will generally be more visible on darker colored papers. Pigment-based inks, however, tend to be... "thicker" or heavier or more dense. In some inkjet printers, it simply won't work. In some it'll work but will jam up the print heads rapidly. Even in printers designed specifically to use pigment-based inks, white can still be difficult to work with and require much more care and maintenance.
2. With most software, even artists software, you typically cannot just have white on screen and print it as such. The easiest way is to replace black with white and make what you want white appear black on screen. In some software, you can also re-key your color space to CMYW rather than CMYK (though the K stands for key regardless of the color, it's typically black and so CMYW is a common placeholder for K = white). Otherwise, anything that's white on screen will not trigger any cartridge or tank to print anything.
3. If this is something you may need to do regularly, it might be worth looking into dye-sublimation printers. I'm not really so sure what the market looks like for this anymore, but many, many years ago I had an Alps printer that could do this - print in white, or print in white then another color to make the color stand out on black (basically print in whi
