Hey Lori,
Sorry to hear about the frustrating experience.
Printing pdf issue is not related to the subscription service, as whether you have the subscription or not you should be able to print the pdf using Adobe Reader DC desktop application.
Thanks for trying the troubleshooting steps and sharing them. As you already tried installing the latest patch released, then might be a the clean uninstall and reinstall of the application will fix the problem.
Cleaner Tool- Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Download Reader- Adobe Acrobat Reader DC Install for all versions
If you would like to continues using the free app, then you can look for the further troubleshooting steps here- Troubleshoot PDF printing in Acrobat and Reader
