I think you have to use QuickBooks Desktop, which has had this feature for about 20 years.

Can you explain how to do this on Desktop?

We're in Canada - thanks.

(I read that a few years ago this was only available to US customers.)

In QuickBooks Desktop (QBDT), the ability to add an electronic signature to checks is currently available only in the US version and is not supported in the Canadian version. No worries, @Ontree, you can consider using a third-party application or electronic signature service that integrates with QuickBooks Desktop to add your signature to checks.

You can open this link to view the QBDT webpage: https://desktop.apps.com/home.

Once on the page, follow the steps below: 

1. Go to All Applications.
2. On the search tab, type in the clue word of the specific app you're looking for.
3. Click the magnifying glass to search. 

I appreciate your understanding regarding the availability of the electronic signature feature. If you have any other questions about QBDT, please feel free to reach out. We’re always happy to help you get the most out of your software.

That's too bad - it's really a feature that QB should have.

I did as you suggested and typed in 'signature' to search around & found nothing comparable or relevant that was a reasonable EXTRA cost.

Oh well.
