Can the printing layout of New Outlook be adjusted?

For your needs, including landscape printing layout and calendar item display, I suggest submitting your feedback through Help > Feedback at the top of New Outlook. Additionally, you can post your suggestions in the dedicated New Outlook forum ( Outlook (new) · Community ), where you might receive an official response from Microsoft.
