"Print to PDF" feature disappears after performing a Windows 10 software update

After I did a Windows 10 software update recently, I found that the option to "print to PDF" had disappeared

solution:
(1) Press "Windows Key" + "R"
(2) type in "optionalfeatures.exe", and press enter
(3) check the box for "Microsoft Print to PDF", and press enter

This should resolve the problem
