The document provides instructions for using a barcode scanner and printer to register pesticide applicators for recertification training events. It describes setting up the equipment and database, and outlines four scenarios for registering attendees: 1) scanning an ID card, 2) printing a new card without one, 3) looking up a participant who forgot their card, or 4) keeping a separate list for those without a license. The process automates populating an attendance form for reporting to the state database.
