Using latest Canon MF260 Series URFII LT driver on Windows 10...
When I print a PDF and select "Print in grayscale (black and white)" on the Adobe print dialog, and there is colored text (red/blue/yellow) in the document it always prints too light gray on the document and is barely readable.
Is there a setting that just prints ALL text on a document/webpage always as "Black" NOT grayscale on a non-color canon laser printer?
The grayscale will usually change the color to a shade of gray and not black. The darker the color, the darker the shade of gray will be. In this situation, you can try changing the color in the printer properties window for the MF264. You can change it to black and white from the quality tab.
