A family of Microsoft word processing software products for creating web, email, and print documents.
If you need to have the sheet content able to be updated it must be inserted as a Linked or Embedded Object, not as a Picture or a PDF. As I wrote, however, an Object of either type cannot be rotated. The page containing the Object needs to be set off by Section Breaks which enable changing the Orientation of the page in only that Section to Landscape. If necessary, see Word Help on the subject entitled Change page orientation as well as other topics concerning Section Breaks.
Note: Whenever Section Breaks are used to vary Margins, Orientation, or certain other Layout parameters it can cause considerations when printing [or generating a PDF]. Many printers do not like to change those parameters 'on the fly' so the document may have to be printed in segments based on the Sections where those variations occur.
For automatically updating the link when the document is printed, go to Word> Preferences - Print, then check the box to Update Links. There is a similar check box in Word> Preferences> General to have links update each time the Word document is opened.
