Am I able, and how do I print the customer's invoice with the new format?

Hello there, herrhammers. 

I'd be glad to assist you today in printing your customer's invoice with the new layout in QuickBooks Online (QBO). There's two ways on how to do it:

In the Invoice window.

1. Select PDF view.
   
2. Click Print and download.
   
3. You will be prompted to the PDF page and then click the Print logo.
   

Additionally, in the Invoice tab.

1. Under Action, click the drop-down arrow.
   
2. Select Print.
   
3. You will be prompted to the PDF page and then click the Print logo.
   

Additionally, you can check this article to help you customize the appearance and layout of your sales forms to enhance your business communications: Customize invoices, estimates, and sales receipts in QuickBooks Online.

You can always get back to me here if you have any other questions about invoices. I'll be around to lend a hand. Have a lovely day.
