Hello, jolene12. 

Welcome to the Community. If you're using QuickBooks Desktop, you can print the company address and electronic signature on blank checks. Simply visit our Apps Center and choose a program which can be integrated into QuickBooks Desktop for managing and printing blank paper checks. 

Next, let me show you how to create an electronic signature by following these steps: 

1. Write your signature on a piece of paper.
2. Scan and save the image in the correct file format: BMP, JPEG, PNG, and TIFF.

After that, you'll need to select both Print company name and address and Print Signature Image on the Print Checks window. 

Here's how:  

1. From the File menu, select Printer Setup.
2. In the Form Name drop-down list, select Check/Paycheck.
3. Put a check mark on Print company name and address and Print Signature Image.
4. In the Signature dialog box, choose File.
5. Select the graphics file that contains the signature then click Open.
6. Click OK in the Signature dialog box.
7. Tap OK in the Printer Setup dialog box.

However, If you referring for QuickBooks Online, we're unable to include the company address, and signature on a check in QuickBooks Online. You can consider purchasing pre-printed checks in the QuickBooks Checks & Supplies page for this matter.

You can visit them through this link: QuickBooks Checks & Supplies.

For future reference, I've also included this link to know more details about ordering checks, tax forms, and other supplies.

Please know that I'll be always here to help you if you have any other questions about printing checks, just add a post/comment below. Have a wonderful day ahead and stay safe!
