It’s possible to use the non-visual RichEditDocumentServer component to adjust the required document settings. Create a new document using RichEditDocumentServer and adjust its page by using the corresponding API.

Refer to the following documentation articles, where you can learn how to set the required properties: Document, DefaultCharacterProperties.

This example demonstrates how to set a document page’s landscape, paper kind, margins and font properties.
