Page Designer - Multiple pages not printing

Hi. I have created a template on page designer that allows me to print off labels with content from my records. Each record has up to 8 labels (split across two sheets of A4). Looks amazing but when I try to print, only the first page is printing? How do I get the additional pages to print? I have tried changing print and page sizes to ‘lengthen’ the custom page to the equivalent of two A4 sheets but it didn’t work. Is this only a one page tool?
