Thank you for posting your concern here in the Community, @andy1033. 

I'd like to share what I know about printing checks in QuickBooks Online (QBO). 

The availability of some features in QBO depends on the user type and your access limit. I recommend asking your admin what user type you are. 

If you are a standard user, check the screenshot below to know what you can and can't access: 

If your access should have the option to print checks, you may be experiencing some browser issues. We'll perform some basic troubleshooting to fix it. Let's start with logging into your account through a private browser. It's the best spot to isolate web issues.

• Google Chrome: press Ctrl + Shift + N 
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If you can create a budget successfully using the private browsing session, go back to your regular browser and clear its cache to refresh the program. We advise our users to delete them now and then to prevent and fix issues like this.

Here's an article about verifying that an invoice was emailed and read by the recipient for additional reference.

Please let me know if there's anything else I can help you with printing checks. Thanks and have a great day!
