We appreciate you for joining the thread, @jirina. I want to share some information about QuickBooks Desktop's Print as function.

Currently, the ability to enter a Print as name is only available for vendors. Simply enter a name in the PRINT NAME ON CHECK AS box from the vendor Payment Settings. This is how the name of the vendor will show up on checks. 

Let me walk you through how:

1. Open the Vendors menu and select the Vendor Center.
2. Click on the Pencil icon on the Vendor Information page.
3. Go to the Payment Settings tab.
4. In the PRINT NAME ON CHECK AS box, enter the name how you want your vendor's name to show.
5. Once done, click on OK.

See this image for reference:

• Create an automatic recurring payment (check) to a vendor

Please let me know if this goes so we can help you further with checks, printing, or QuickBooks. Keep safe always!
