Hi Tammy

Good question

Do the following to accomplish the above:

1. Go to Order Defaults | Sales order tab

2. In here unselect the Print all Order Lines options marked below and then select the Print for Processed Orders option

3. When done, click the OK button below to save your changes. 

4. When you now process a new Sales Order Invoice, or reprint an existing processed one, you'll notice that only the processed lines will be included on the print.

Kind Regards

Bennie
