I have a simple goal: I want that a new Block added to my FlowDoc is always in the next row and if the first page is full, then skip to the next page (> Row 59). But if I run my code, the document seems to be divided into two columns and Row 60 appears on the first page (right) and not on the second (what I want to). Can anyone help me with this? Thank’s a lot.Screenshot

  private void Button_Click(object sender, RoutedEventArgs e)
  {
      FlowDocument flowDoc = new();

      flowDoc.FontFamily = new FontFamily("Arial");

      flowDoc.FontSize = 12;

      flowDoc.PageWidth = 755;
      flowDoc.PageHeight = 1150;
   
      flowDoc.PagePadding = new Thickness(60, 50, 60, 50);

      flowDoc.LineHeight = 4;

      for (int i = 0; i < 100; i++)
      {
          flowDoc.Blocks.Add(new Paragraph(new Run($"Row {i + 1}")));
      }

      PrintDialog pd = new();

      if (pd.ShowDialog() == true)
      {
          IDocumentPaginatorSource idpSource = flowDoc;

          pd.PrintDocument(idpSource.DocumentPaginator, "Print Page");
      }
  }
