But in this case we should not even try to print something, since we checked at the beginning that there are no printers.

I decided to check by eyes what happens on the system:
  - The system has a few printers, and default one is "print to pdf".
  - When the test is executed the printer promts the location to where store the pdf file(probably this location can be set to some default and we will able to test printing as well at someday)
  
BTW this windows system was soooo slow so I was not able to move the mouse to select the file location, and have to reboot it....
