How to do silent printing to print the Word document by rendering document pages as Image using Essential DocIO?
Essential DocIO supports to do silent printing to print the Word documents using System.Drawing.Printing namespace of .NET Framework Class Library.
First step is to render the Word document content as images as shown below using Essential DocIO.
C#:
// Load the word Document WordDocument doc = new WordDocument(@"..\..\Template.docx"); // Convert Word Document into image images = doc.RenderAsImages(ImageType.Metafile); doc.Close(); |
VB:
' Load the word Document Dim doc As New WordDocument("..\..\Template.docx") ' Convert Word Document into image images = doc.RenderAsImages(ImageType.Metafile) doc.Close() |
Second step is to do silent printing to print the Word document pages that are rendered as images by Using PrintDocument property. It helps to do the complete printing using PrintDialog with default printer settings, page settings and print the document by invoking the PrintDocument.Print method. Kindly refer the blog for more details to print the Word document with custom printer settings.
Below code snippets demonstrates how to do silent printing to print Word documents by rendering document pages as image:
C#:
//Create a PrintDialog System.Windows.Forms.PrintDialog printDialog = new System.Windows.Forms.PrintDialog(); //dialog.PrinterSetting printDialog.Document = new PrintDocument(); //Retrieve the Page need to be rendered printDialog.Document.PrintPage += new PrintPageEventHandler(OnPrintPage); //Print the document printDialog.Document.Print();
/// <summary> /// The PrintPage event is called for each page to be printed. /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected virtual void OnPrintPage(object sender, PrintPageEventArgs e) { //Current page width int currentPageWidth = images[startPageIndex].Width; //Current page height int currentPageHeight = images[startPageIndex].Height; //Visible clip bounds width int visibleClipBoundsWidth = (int)e.Graphics.VisibleClipBounds.Width; //Visible clip bounds height int visibleClipBoundsHeight = (int)e.Graphics.VisibleClipBounds.Height; //Draw the current page e.Graphics.DrawImage(images[startPageIndex], new System.Drawing.Rectangle(0, 0, visibleClipBoundsWidth, visibleClipBoundsHeight));
//Dispose the current page images[startPageIndex].Dispose(); //Increment the start page index startPageIndex++; //check if the start page index is lesser than end page index if (startPageIndex < endPageIndex) e.HasMorePages = true;//if the document contain more than one pages else startPageIndex = 0; } |
VB:
'Create a PrintDialog Dim printDialog As New System.Windows.Forms.PrintDialog() ' dialog.PrinterSetting printDialog.Document = New PrintDocument() 'Retrieve the Page need to be rendered printDialog.Document.PrintPage += New PrintPageEventHandler(OnPrintPage) 'Print the document printDialog.Document.Print()
''' The PrintPage event is called for each page to be printed. Protected Overridable Sub OnPrintPage(sender As Object, e As PrintPageEventArgs) 'Current page width Dim currentPageWidth As Integer = images(startPageIndex).Width 'Current page height Dim currentPageHeight As Integer = images(startPageIndex).Height 'Visible clip bounds width Dim visibleClipBoundsWidth As Integer = CInt(e.Graphics.VisibleClipBounds.Width) 'Visible clip bounds height Dim visibleClipBoundsHeight As Integer = CInt(e.Graphics.VisibleClipBounds.Height) 'Draw the current page e.Graphics.DrawImage(images(startPageIndex), New System.Drawing.Rectangle(0, 0, visibleClipBoundsWidth, visibleClipBoundsHeight)) 'Dispose the current page images(startPageIndex).Dispose() 'Increment the start page index startPageIndex += 1 'check if the start page index is lesser than end page index If startPageIndex < endPageIndex Then e.HasMorePages = True Else 'if the document contain more than one pages startPageIndex = 0 End If End Sub |
