Hi there, @Zeugin .
A fix has been implemented by our product engineers for the issue with printing or previewing checks. Since you can't still print or preview checks, let's perform some troubleshooting steps to make the fix flow into your account.
Try logging into your QBO account using a private browser. There are times that the browser is full of frequently accessed page resources, thus causing some errors and/or unusual responses.
To use a private browser, here's how:
- Google Chrome: Ctrl + Shift + N
- Internet Explorer: Ctrl + Shift + P
- Mozilla Firefox: Ctrl + Shift + P
- Safari: Command + Option + P
Once logged in, go back and try to print or preview checks again to double-check. For your reference, you can read this article for further guidance: Print Checks.
If this works, it means that you need to clear your browser's cache so the system can start fresh.
If you get the same result while using a private browser, I recommend switching to a different browser.
