Because of the multi panel view design, you need to click the area where you indent to print before you click the Print button. This is to ensure the correct printout.
If the printing consists of too many pages, the system will prompt you a dialog showing the page range. You may want to change the printing range.

Example above, if you want to print only the 1st page, you need to change 1 to 1 page. Alternatively, you may want the last display page only, then you can change it to page 14 to 14.
You can also preview the printing before sending it to printer. This will allow you to judge which page to print.
