private void PrintDocument(object sender, RoutedEventArgs e)
        {

            var printers = new LocalPrintServer().GetPrintQueues();
            var selectedPrinter = printers.FirstOrDefault(p => p.Name == "Microsoft Print to PDF");
            if (selectedPrinter == null)
            {
                MessageBox.Show("Printer not found!");
                return;
            }
            pDialog.PrintQueue = selectedPrinter;
            FixedDocument fixedDoc = new FixedDocument();
            PageContent pageContent = new PageContent();
            FixedPage fixedPage = new FixedPage();
            fixedPage.Width = 1056;
            fixedPage.Height = 816;
            var gridToRemove = scrollViewerOfTable.Content as Grid;
            if (gridToRemove != null && gridToRemove.Name == "gridOfCreatingTableOfCloth")
            {
                scrollViewerOfTable.Content = null;
                fixedPage.Children.Add(gridToRemove);
                ((IAddChild)pageContent).AddChild(fixedPage);
                fixedDoc.Pages.Add(pageContent);
                //Create any other required pages here
                DocumentViewer documentViewer1 = new DocumentViewer();
                //View the document
                scrollViewerOfTable.Content= documentViewer1;
                documentViewer1.Document = fixedDoc;
                pDialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
                pDialog.PrintTicket.PageMediaSize = new PageMediaSize(fixedPage.Width, fixedPage.Height);
                IDocumentPaginatorSource paginatorSource = documentViewer1.Document as IDocumentPaginatorSource;
                DocumentPaginator paginator = paginatorSource.DocumentPaginator;
                paginator.PageSize = new Size(fixedPage.Width, fixedPage.Height);
                pDialog.PrintDocument(paginator, " ");
            }
        }

Help edit the code. My code renders everything correctly, but when the grid is too big, it gets cut off and doesn't show up on other pages.

Hi,@vitaminchik. You could use the following code.

     private void SaveDocumentOfTable(object sender, RoutedEventArgs e)
        {
            PrintDialog pDialog = new PrintDialog();
            var printers = new LocalPrintServer().GetPrintQueues();
            var selectedPrinter = printers.FirstOrDefault(p => p.Name == "Microsoft Print to PDF");
            if (selectedPrinter == null)
            {
                MessageBox.Show("Printer not found!");
                return;
            }
            var gridToRemove = scrollViewerOfTable.Content as Grid;
            pDialog.PrintQueue = selectedPrinter;

            pDialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
           
         
            if (gridToRemove != null && gridToRemove.Name == "gridOfCreatingTableOfCloth")
            {
                scrollViewerOfTable.Content = null;

                FixedDocument fixedDoc = PrintHelper.GetFixedDocument(gridToRemove, pDialog);
             

                DocumentPaginator paginator = fixedDoc.DocumentPaginator;
           
                pDialog.PrintDocument(paginator, " ");
            }
        }

PrintHelper:

 public static class PrintHelper
    {

        public static FixedDocument GetFixedDocument(FrameworkElement toPrint, PrintDialog printDialog)
        {
            PrintCapabilities capabilities = printDialog.PrintQueue.GetPrintCapabilities(printDialog.PrintTicket);
            Size pageSize = new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight);
            Size visibleSize = new Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight);
            FixedDocument fixedDoc = new FixedDocument();
            //If the toPrint visual is not displayed on screen we neeed to measure and arrange it  
            toPrint.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));
            toPrint.Arrange(new Rect(new Point(0, 0), toPrint.DesiredSize));
            //  
            Size size = toPrint.DesiredSize;
            //Will assume for simplicity the control fits horizontally on the page  
            double yOffset = 0;
            while (yOffset < size.Height)
            {
                VisualBrush vb = new VisualBrush(toPrint);
                vb.Stretch = Stretch.None;
                vb.AlignmentX = AlignmentX.Left;
                vb.AlignmentY = AlignmentY.Top;
                vb.ViewboxUnits = BrushMappingMode.Absolute;
                vb.TileMode = TileMode.None;
                vb.Viewbox = new Rect(0, yOffset, visibleSize.Width, visibleSize.Height);
                PageContent pageContent = new PageContent();
                FixedPage page = new FixedPage();
                ((IAddChild)pageContent).AddChild(page);
                fixedDoc.Pages.Add(pageContent);
                page.Width = pageSize.Width;
                page.Height = pageSize.Height;
                Canvas canvas = new Canvas();
                FixedPage.SetLeft(canvas, capabilities.PageImageableArea.OriginWidth);
                FixedPage.SetTop(canvas, capabilities.PageImageableArea.OriginHeight);
                canvas.Width = visibleSize.Width;
                canvas.Height = visibleSize.Height;
                canvas.Background = vb;
                page.Children.Add(canvas);
                yOffset += visibleSize.Height;
            }
            return fixedDoc;
        }

        public static void ShowPrintPreview(FixedDocument fixedDoc)
        {
            Window wnd = new Window();
            DocumentViewer viewer = new DocumentViewer();
            viewer.Document = fixedDoc;
            wnd.Content = viewer;
            wnd.ShowDialog();
        }

    }

The result:
