Thanks for joining in this thread @kdb1213.

The information that'll appear on the printed check is the same as what you've entered in the vendor account.

To resolve the issue, remove unnecessary details in the vendor name. Let me help you how. 

Here's how:

1. On the left pane, select Expenses. 
2.  At the top left, select the Vendors tab. 
3. Find and click the vendor's name. 
4. At the top right, click Edit. 
5. On the Print on check as field, do not fill neccesarry information under Fist Name, Middle Name, and Last Name.
6. Click Save.

There you'll go you can print the check without the vendor contact person name.
