Hello, ulift2015. 

Thank you for reaching out to the community. Printing a memo on the check is super easy. However, if you don't have input in your memo field yet, simply open the check and manually enter the memo onto the check. 

1. Go to the Expenses menu on the left panel, then Expenses.
2. Open the check that has the memo you want to appear on the printed.
3. Click Print Check. 
4. Press Preview and Print. 
5. Hit Print. 

For your reference, you can check out this article to know more about what you can and can't print in the memo field: When the memo field will and will not print. 

I am all hands open here if you need further help with printing your checks. I'll get back to you as soon as I can.
