Hello Rob,

Thank you for contacting PDF.js Express Forums.

We need some more information to better assist you.

1. What version of the viewer are you using?
2. Are there any console/network errors?
3. How are you printing the document? Are you using one of our APIs?
4. Was this working previously without issue?

Best Regards,Darian

Only console message is: webviewer-ui.min.js:68 react-i18next:: It seems you are still using the old wait option, you may migrate to the new use Suspense behaviour.

We’re printing from the settings menu icon, print.

Yes everything was working fine before, we have not updated anything.
