Thanks for visiting us and letting us know about this, @Kellie24,

While this thread has multiple discussions for printing checks in QuickBooks Desktop and Online, may I know which product are you using? I need this information so I can provide the best resolution to resolve this problem.

In the meantime, if you have QuickBooks Online and having trouble printing checks, make sure your laptop meets our system requirements. You also need an updated Adobe Reader version 11.0 or higher to print forms. Then make sure the desired printer is set as the default printer on the new device.

If everything meets the required specifications and still won't allow you to print, follow the troubleshooting steps found in this article: Troubleshoot Issues with Printing and .PDF Files

Lastly, if none of the steps work, please contact our live support immediately to report this. Here's how: 

1. Go to the (?) Help menu and click on Contact Us.
2. Enter the keyword Account Management and Billing in the What can we help you with? box.
   
3. On the next screen, scroll down to the Choose a way to connect with us section.
4. Choose Start messaging to initiate a discussion with a live agent or Get a call for callbacks.
   

When using the messaging option, a small discussion box will open at the bottom right section of your monitor. An agent will be with you after filling in the information. See this:

I'll be waiting for your response on how things will go. I'm also here if you need further help with anything in QuickBooks. Have a nice day!
