Thanks for posting here in the Community forum, @windyl0u. To print all paid transactions in QuickBooks Desktop, you'll need to click the Invoices button under the Print Selected column and proceed with the batch printing.
To clarify, those greyed options are title columns only, so once you click Invoices, it will let you print those transactions in batch.

The clarification I've shared above will help you print those transactions. If you have any further questions or need additional guidance, don’t hesitate to reach out. I’m here to help! Thank you for using QuickBooks Desktop, and have a great day!
