How to save checks and multiple prining of checks

Good morning, @jmf2949-gmail-co.

Thanks for taking the time to reach out to the QuickBooks Community. I hope you're having a great day so far. 

If you'd like to print multiple checks at once, you'll need to ensure that each check has the Print Later box checked as shown in my screenshot below. 

To print the checks: 

1. Click the + New button, then select Print Checks.
2. Choose the appropriate bank account containing the checks you created.
3. Add a checkmark to the checks you want to print.
4. Hit Preview and print.
5. Then, click Print.

That should do the trick. For more information about this process, check out: Print a check in QuickBooks Online. 

Please don't hesitate to let me know if you have any follow-up questions or concerns. I'm always around to lend a hand. Have a good one!
