Let's perform some troubleshooting steps so you can print your reconciliations report successfully.
It's very unusual to print a reconciliation report with a blank page. Let's try logging in to your QuickBooks Online (QBO) account via a private browser. It's a good start to check if it's a browser data issue.
To use a private browser, here's how:
Once logged in, go back and try to print the reconciliation report again to double-check. For more guidance, feel free to check out this article: How do I view, print, or export a reconciliation report?
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 updating, repairing, or re-installing Adobe Reader/Acrobat.
