The correct answer is to check and update the printer driver settings. Often, printer drivers can override application settings leading to incorrect page orientations, regardless of the document's formatting. Updating or reconfiguring the driver typically resolves this conflict. Checking the physical printer settings might not be as effective because the issue occurs across multiple documents and user settings which are already verified. Resetting the application preferences would not resolve the issue if the printer driver is the cause. Lastly, changing the document orientation would only provide a workaround and would not solve the underlying problem with the printer or its drivers.
