RichTextEdit controls
The Document Name property specifies the name that appears in the print queue when the user prints the contents of the control.
To set the document name for printing:
Enter the document name in the Document Name for Printing field on the Document tab page of the control’s Properties view.
The DocumentName property takes a string. The following example specifies a document name for the print queue for a RichTextEdit control:
rte_1.DocumentName = "Report 1"
