Hey there, rtrujillo.

Let me help you with printing and emailing invoices in QuickBooks Desktop.

In order to print your client's invoices, you'll use the Print Later option in the invoice screen and make sure that the Email Later is not selected.

For the invoices that need to be emailed, pick the Email Later option instead.

This way, you'll be able to isolate the invoices that are for print and for email. 

Keep me posted with any further questions. I'll be right here to lend you a hand.
