You have an ALPS PRINTER!!!!!!!!!!!!!!!!!!!!!! We gotta talk about getting you a white printer ribbon.

And a black one. I did test print in black, before printing in white. Also, the white ribbon, has to have the "identifier sticker" from a black ribbon, to print. I never did figure out how to tell the printer "how" to print white.
If you can find a reasonable source, let me know.
