Windows 10 Version 2004 printer woes - solution?

 After the recent Windows 10 2004 feature update, users who applied that update suffered issues with printing. Not just printers but printing. Some user reverted to a previous Windows 10 version and the printing problems resolved.
 Some users desired to keep the features provided by the 2004 feature update, had no printing issues, or resolved to do workarounds until the July schedule B update was issued.
 If you are the few who wish to have the feature update and less printing problems, KB4567523 might be for you.

 The update/fix will not be available via Windows Update but users can "seek" the update, apply to their machines, and enjoy both feature updates and printing.

 Seek the cited KB4567523 at the Microsoft site.


NOTE: Searching for the KB4567523 patch via search engines will yield several non-Microsoft sites offering A KB4567523 patch, not THE patch. Better practice to get patches from the Microsoft Update Catalog.



You will need to choose the correct patch for your system.
