I used to be able to print a PDF to black and white (grayscale is of no use to me) right in the print dialog window, but once I updates, that feature was replaced with a note that says "Click the Properties button" to change the color setting using the specific printer driver - which, in my case, is the PDF printer driver - but it doesn't work.
Any work-arounds or ways to revert my version to the previous one?
In the Acrobat dialog, when Adobe PDF is selected as your printer, click on the Advanced button and select Color management on the left-hand panel. Under the Color Profile dropdown try selecting Black & White. Just remember to set it back to the default when you need to print color again.
