Hello Ertuğrul,
please see the example below.
Suppose you have a catalog "Products" and the image is stored in the "DataPicture" attribute (screenshot 1).
We also have a SpreadsheetDocument that has an Image element named D2 (screenshot 2). In this case, the source code for printing the image will look like this:
| Code | 
|---|
| &AtClient
Procedure cmdPrint(Command)
   
   PrintDocument = PrintAtServer();
   
   PrintDocument.Show(PrintDocument);
   
EndProcedure
&AtServer
Function PrintAtServer()
   
   PrintDocument = New SpreadsheetDocument;
   
   Template    = Catalogs.Products.GetTemplate("Template");
   PictureArea = Template.GetArea("PictureArea");
   
   Picture = New Picture(Object.Ref.DataPicture.Get());
   
   PictureArea.Drawings.D2.Picture = Picture;
   
   PrintDocument.Put(PictureArea);
   
   Return PrintDocument;
   
EndFunction
