How do I print all text as black?

I have Adobe Acrobat Reader "Continuous Release | Version 23.008.20555.0 | 64-bit" running on Windows 10 Pro.

I have a pdf file containing only text.  Some of this text is gray which is difficult to read when printed on my monochrome laser printer.

I would like to print everything as BLACK.  Not just monochrome, BLACK.  Color code "HEX: #000000".  

I've found several ways to do this with older versions of Acrobat Reader, but they do work with this version.

Is this possible?  If so how.

My old eyes would be very grateful for a solution.
