Hello there, Nobuko1.
 
We can do some troubleshooting steps to resolve the print and preview issue in QuickBooks Online (QBO).
 
Before we proceed, could you clarify what you are trying to preview and print in QuickBooks? Any details you can share will help me understand your concern better and provide an accurate solution.
 
In the meantime, we can have your user clear the browser's cache. Cached files can sometimes cause compatibility problems and prevent successful connections. By doing this, we are giving their browser a fresh start to help resolve the issues when accessing the preview and print features.
 
Additionally, make sure you're using a supported browser for optimal compatibility with QuickBooks.
