It is difficult to say what goes wrong in this case, since the print preview seems to show that the design can be printed without problems. I would advice to install a so-called PDF Printer, which is a piece of (free) software that you can download. With that you can "print" your design to a PDF file and see if that produces the correct result.
You can find many free PDF printers through Google, most are free but usually come with some extra unwanted bits that you may want to uncheck during installation.
