Actually I think the separate ink cartridges was a great idea, but it’s true that my computer still wants yellow when printing a black and white document. In my printer settings everything is set to grayscale with no color settings whatsoever and yet I still get an error message telling me I can’t print unless I have one of the colors. I figured out that if I just pause the printer queue and resume it, the printer will print it out with no fuss at all. I have to do it every single time I print, but I like it because I feel kind of like I’m tricking the computer.
