I'm here to help ensure you're able to print the paper checks.
Let ensure the Adobe Acrobat or Reader installed on your computer is updated. Outdated versions of Adobe might not work when trying to print pay stubs and sales forms. To update, please refer to the link under How to update Adobe Reader/Acrobat in the following article: How to update, repair, or re-install Adobe installations.
After updating, set it as the default PDF viewer for your browser. This is to make sure you're using the updated version when printing the transactions in QuickBooks.
