Hi there
We are sorry to hear that. What is the version of the Acrobat Reader DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version 20.12.20048 installed. Go to Help > Check for Updates and see if that helps.
Also, please check for any missing/pending updates for the printer driver and firmware.
You may please try to repair the installation (Windows Only) from the help menu and see if that works. Go to Help > Repair Installation.
If it still doesn't work, please try to turn off the security (Windows Only) for testing. Go to Edit > Preferences > Enhanced Security > Uncheck 'Enable protected mode at startup', turn off the protected mode and uncheck enhanced security > click ok and reboot the computer.
Note: Turning off the security may possess security risks, please turn on the security after testing.
If it still doesn't work, please reset the preferences to default as described here https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082?page=1 and check.
Let us know how it goes
Regards
Amal
