After printing something in the landscape mode I can't change to portrait mode. What should I do?

• 1. Click on START, go to SETTINGS, and click on PRINTERS.
  2. Right click on your EPSON CX5200 icon, and then click on Preferences.
  3. Select Paper and change the Orientation to whatever you require.
  4. Click on APPLY at the bottom of the window.
  
  Your changes have now been saved, and are now the default. You will have to repeat this process any time you wish to make changes to the settings of your printer.
