Yes, on the left hand side of the events grid there is a blue print icon on each row. Clicking this icon will generate a PDF file of the tickets from that purchase. You can then save these tickets or print them. Or if you need to sent the tickets out through email to the purchaser you can click the blue envelope Icon to the right of the printer icon.
You can also resend all the tickets by using the Actions menu and clicking on Resend Tickets. Note this is limited to sending batches to 100 registrants at a time. If you have more than 100 registrants (purchasers, not attendees) you will need to filter your list by ticket level or date to ensure the grid does not show more than 100 registrants at a time.
