1. Do you want to edit pages in the way they will be printed? It is possible in ScaleRichView.
2. Size of what? If you mean a page size and page margins, they are defined (in ScaleRichView) in TSRichViewEdit.PageProperty. If you will use RichViewActions (ready-to-use user interface actions and components), you can define them in actions TsrvActionPageSetup and others.
