Thanks for reaching out to us, ChetAsher.
I'll provide you with some information so you can print the routine and the bank account number on a blank check.
The ability to print bank details onto check stock isn't available in QuickBooks. However, PrintBoss can print the account and routing number onto the MICR line of blank check stock as a QuickBooks add-on software.
Simply integrating it with QuickBooks Desktop is all that is required. Then, you may create a bank record using the PrintBoss wizards. I recommend contacting their support so they can assist you in setting up your bank details. They can help you through the procedure since they're familiar with their application.
Once done, select the PrintBoss printer in QuickBooks since it will show as a printer driver when printing checks. This is what makes the PrintBoss-QuickBooks integration so simple and effective.
If you have problems printing, please refer to this article to learn how to solve it: Fix printing issues in QuickBooks Desktop.
You're welcome to post again if you need anything else. Have a great day.
