Jarrett asked 2 month ago Fashion Why doesn’t my 4 color printer print in black when the yellow toner is empty? View +3 answers Report
Because that way they couldn’t get you to buy as much colored toner.
You can try changing the settings to print in Greyscale, it may print then?
Several possibilities: You have a cheap printer with cheap components and badly-written drivers, Actually that’s pretty much it. You can try telling it to print in black-and-white, specifically (if your driver allows that).
