Which printers print directly from RAW?

all of them.

Proof?

open raw image. choose print from the menus. collect print from printer.

Open raw image in what?

any of a variety of apps, including photoshop, llightroom, dxo, nikon
or canon's own software, etc.

it's your choice.

obviously it needs to support raw from your camera. microsoft excel
would be a bad choice.
