Hello, MickeyK.

Thank you for taking the time to set up the alignment when printing vendor checks by following the instructions provided above by my colleague. I'll share some troubleshooting procedures to determine if this is an issue with the QuickBooks program or the preprinted checks.

Let's download and install QuickBooks Tool Hub. Then, you can run the QuickBooks PDF & Print Repair Tool to resolve any printing-related issues with the program. I'll show you how.

1. Close QuickBooks.
2. Download the most recent version (1.5.0.0) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it.
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. Once done, double-click the icon on your Windows desktop to open the tool hub.

Once installed, run the QuickBooks PDF & Print Repair Tool from the tool hub.

Here's how:

1. In the QuickBooks Tool Hub, click Program Problems.
2. Select QuickBooks PDF & Print Repair Tool. 
3. Attempt to print, email, or save as a PDF from QuickBooks Desktop again.

If the same, the preprinted check you have isn't QuickBooks formatted. I recommend purchasing a preprinted check directly from the IntuitMarket website. 

I'm also adding this article for your reference: Create, modify, and print checks.
