I'll show you how to add the Bill to and Ship to addresses so you can print with your packing slips, Suzannehy.

I can see how the new layout doesn't fold in a way that shows the Bill to and Ship to addresses in the packing slip window. However, with the latest update, the fields are now available and you can already add the addresses on the fields. I've added a screenshot for your visual guide:

1. Go to the Sales menu, then select Customers.
2. Locate the invoice and click Edit.
   
   
   
   
3. Click Save.

Once done, the information will now show up when printing. 

You'll want to print them and manually add them to the packing slip or envelope.

Additionally, QuickBooks provides tools to create invoices, estimates, and sales receipts the way you want them to be. To give more details, review this article for reference: Customize Invoices, Estimates, and Sales Receipts in QuickBooks Online.

Let me know if you have other concerns when creating packing slips or if there's anything else that you need help with when customizing forms. I'm always one post away if you need further assistance.
