Halloween printables idea is Keepsakes. Kids they can use these special pages to make a scrapbook of their memories of trick_or_treat. Once the kids add photos of their spooky adventures, the book will serve a nice keepsake for years to come.
Another important thing to remember is making sure that you have enough ink in your printer. This includes color and black depending on what kind of game you decide to print out. Allow the print out enough time to dry before picking it up, some games will use a lot of ink and it may still be damp when it's done printing.
