Yes, this is helpful when you don't want to print all the badges at once. On the print screen select the attendees you wish to generate a PDF for and then print it.
For this example let's say I want this first batch to include Sam Dalton, Michael Jameson and Lisa Schwartz. So I select their name and click on Create badges for 3 attendees.
The system will generate a PDF document ONLY for these 3 attendees. You can then download the file and print it.
It will also remove this people from the unprinted list on the right side of the screen, this way you can keep track of the badges that are not yet printed.
