Intuit's own instructions:

Troubleshoot PDF and Print problems with QuickBooks Desktop

https://quickbooks.intuit.com/learn-support/en-us/help-article/manage-users/troubleshoot-pdf-print-p...

are antiquated and only reference Windows Vista, 7, and 8 in "Solution 4: Test, reinstall, and adjust permissions for XPS Document Writer, Step 3: Reinstall Microsoft XPS Document Writer".

They need to include your solution in that article.
