You can insert a blank page into the project, by hitting Add a Page. The page will be added at the end of the print project. You can click and drag it up and down to control where in the print project it will be printed. You can insert a blank page between print jobs, and even inside of an existing print job as long as you have selected the 'Pages' radio button, under the PDF Range. NOTE: You can hit the Insert key to Add a Page.
