Invoice or Estimate is Grouping Items Together when printed but they are separate line items on the invoice screen

Open the System Five Navigator 
Open Setup Tools
Open Printing Options
Open Form and Label Designers
Open Form Designers
Open Invoice Designer

Next select the form you want to edit. My demo only has the default form, but you will select the Estimate form if that is the one that combines the inventory parts when the invoice is printed.
Now click the edit button

This will open the selected form in the invoice designer 
Click on the Options tab
Uncheck the check box next to Summarize quantities for pick list
Click the Save button.

Now when you print the invoice, each item is on it's own line.
