I see the following messages when I try to print: Paper size does not match or Mismatch between the paper size settings. What should I do?

• These errors occur when the paper size setting on the printer differs from the document you are trying to print. Make sure the paper size selected in the printer software matches the paper size selected on the printer's control panel. To verify the paper size on the printer's controlpanel press, Home if necessary, then select Setup > Paper Setup.
  
  If this does not resolve the issue, contact Epson.
