Thank you for posting here in the Community forum. Yes, you can print a description on a check. I'll be happy to walk you through printing checks that show the Description column.
Here's how:
Go to +New.
Select Checks and enter the necessary information.
I'll provide some additional steps on how to get around this matter so you can seamlessly print your checks.
I replicated your concern and I was able to print a check with the entire description.
You can perform browser troubleshooting steps as this concern could be a browser-related issue. First, let's try accessing your QBO account via an incognito/private window. The browser's cache may be full, and using a private browser can help us determine if this is the cause of the issue.
Here are the keyboard shortcuts to open a private browser:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox: press Ctrl + Shift + P
Microsoft Edge: press Ctrl + Shift + P
Safari: press Command + Shift +N
If you're able to print using a private browser, go back to your regular browser and clear its cache. Clearing the cache or cookies is the best way to get a clean slate for your browser. Otherwise, using other supported browsers can be a good alternative too.
If you want to have a pre-printed customized check, you can visit our Intuit QuickBooks Checks and Supplies Team for the best compatibility. QuickBooks Online also has the option for you to align your checks when printing.
