If you set a printer to print white text, does it use ink?
Originally, I was going to add "....on white paper", but other than size, I don't think your common desktop printers can recognize paper color
And how would a printer cartridge printer white text when it has black, magenta, cyan, and yellow ink?
To be clear, I'm not saying that you draw a black box in MS Paint or something with white text. Clearly, the printer would just print the box and omit the ink that makes up the text. But I don't have any non-white paper with me at the moment so I cannot test if a printer can actually print out white-colored text on colored paper
