Hi Pawnshack!
Allow me to help you in printing receipts.
The recommended paper size when printing sales forms in QuickBooks Online is Letter (8.5 x 11 inches). What I can suggest is to look for third-party software that can connect to a receipt printer. That way, you can print it to the desired size.
Please visit QuickBooks App Store to search for supported third-party apps. Please note that these apps may not work in some countries or regions.
I also added this link if you need detailed steps in customising your sales forms: Customise invoices, estimates, and sales receipts.
I'll always be here if you need more help from me. Do you need assistance on how to record payments? Just leave a comment and I'll respond.
