To rotate an entire document to print 90 degrees sideways, you can follow these steps:

1. Open the document you want to print in Microsoft Word.
2. Click on the "Page Layout" tab in the ribbon at the top of the screen.
3. Click on the "Orientation" button and select "Landscape" orientation.
4. Your document will now be rotated 90 degrees to the right. If you want to rotate it to the left, click on the "Orientation" button again and select "Portrait" orientation.
5. Once you have selected the desired orientation, go to the "File" menu and select "Print".
6. In the print dialog box, make sure that the correct printer is selected and click on the "Print" button.

Your document should now print in the desired orientation. Keep in mind that some printers may not be able to print in landscape orientation, so you may need to check your printer's manual or contact the manufacturer for more information.
