Printing a check copy is essential for business operations. I can provide you with detailed information and assistance to help you address this issue effectively.
The way checks are printed depends on your printing configuration. We can review these settings to determine if they are causing the check to print a copy on check stock.
Here’s how you can check your printer setup:
1. Go to the File tab and click on Printer Setup.

2. In the Printer Setup, select Check/Paycheck.

Consider opening one of your QuickBooks sample files to see if it has the same setup as the one you've recently created. If it doesn't match, we can ensure that the printer is set up correctly. Additionally, you can refer to this guide for more help: Fix printing issues in QuickBooks Desktop.
