Hello there, @llroberts.
I can share some information on how to remove the invoices in the Print queue.
You'll have to choose the invoices you want to be removed from the queue by checking them off. Choose Print transactions from the Batch actions. The invoices will open in another Google tab. Instead of printing, you’re going to close the tab that just opened. This takes you back to QBO, you'll be asked if you want to mark the selected transactions as printed. Click Yes. Your print queue should now be empty.
I've added this link about customizing invoices in QBO: Customize invoices, estimates, and sales receipts in QuickBooks Online.
Please know that you can always get back to us if you have other questions. I'm more than happy to help. Take care.
