Welcome to the Community, sealearth70. We'll provide details on how the Print Items in Group functionality works so you can manage your Group Items accordingly.
We agree with your observation. As you are tracking a group of items, the pricing is per line, and QuickBooks will show each of them on your invoices. So regardless of whether the Print Items in Group feature is checked or unchecked, all items and the title will appear on the form. Furthermore, this option will work only when you print your sales transaction.
