Hello there, @RM15.

Let me provide information about using thermal printer in QuickBooks Desktop (QBDT).

Currently the option to use thermal printer in QBDT is unavailable. For now, I recommend exploring third-party applications that offer integration solutions for thermal printers with QBDT. Additionally, you may consider searching the Intuit Marketplace for potential options.

I will also include these articles, which provide guidance on resolving printing issues and offer troubleshooting steps for scenarios where you are unable to print or save documents as PDF:

• Fix printing issues.
• Fix PDF and Print problems with QBDT.

If you have any concerns about the thermal printer or anything else related to QuickBooks, please tag me in the comment section, @RM15. I'll assist you in any way possible.
