Hi userfclcsolutions!
I understand that you need to align the paychecks when you print them. Let me help you.
Currently, we need to configure the print settings for the vendor check and paycheck separately. It's best to purchase and use a preprinted checks from QuickBooks Checks Supplies. This is designed to work seamlessly with QuickBooks Online Payroll and other Intuit products.
Then, update, repair, or re-install Adobe Reader/Acrobat. QuickBooks uses this software when printing documents including paychecks.
I've added some links you can check. These will show you more info on how to print paychecks:
