Verify Adobe Account Activation and Update Acrobat
Refreshing your login session and updating the software often resolves intermittent license authentication conflicts.
License errors during printing frequently occur if the Adobe background authentication service has timed out or if you are running an outdated version of Acrobat.
Open Adobe Acrobat Pro DC, click on the 'Help' menu at the top of the screen, and select 'Sign Out'.
Restart the application and follow the prompts to sign back in using the email address associated with your active Adobe subscription.
Navigate to 'Help' > 'Check for Updates' within Acrobat. Download and install any available updates to ensure optimal compatibility with your browser.
Open a document in Microsoft Word or another web browser like Google Chrome, and attempt to print to Adobe PDF to determine if the issue is isolated to Firefox.

Run a Repair Installation for Acrobat
Repairing the Acrobat installation can fix corrupted PDF printer drivers that cause activation errors when triggered from a browser.
