Unable to check the Print Preview option. ID: [removed]

I'm glad to see you here in the Community, @accounts356.

Let's perform browser troubleshooting steps to resolve the issue. Let's start by using a private browser. Private mode prevents storing cache and cookies that might cause problems when running websites.

You may use the following shortcut keys:

• Google Chrome: click Ctrl + Shift + N 
• Mozilla Firefox and Microsoft Edge: press Ctrl + Shift + P
• Safari: hit Command + Shift + N

When signed in, attempt to click the Print or Preview button. 

If you don't experience the same thing, let's go back to your regular browser and clear the cache. This will remove the stored data to refresh your browser's background process. If the same thing happens, use another supported browser. It could be that the one you're currently using has a temporary issue. 

Here's a great source you can visit to help you personalise the appearance and layout of your sales forms: Customise invoices, estimates, and sales receipts in QuickBooks Online. This also includes steps on editing your email message, turn on online payments for invoices, edit custom templates, etc. 

Keep me posted if you have any other concerns when viewing the print previews of any transactions in QBO. I'm always here to help. Have a great day ahead.
