• How can I flip/rotate a PrintDocument in .NET ?

  - by Simon_Weaver

  I have a document that I want to be flipped / rotated 180 degrees when printed. (This is due to the orientation of label stock in the printer). There is a property PrintDocument.PrinterSettings.LandscapeAngle but it is read only. I think this property is influenced by the printer driver and therefore not 'settable'. Is there a nice way i can rotate the print by 180 degrees without having to do anything too nasty?

• How do I catch the error from my printer with PrintDocument?

  - by Scottie

  I am using the PrintDocument class to print to my Brother label printer. When I execute the Print() method, the printer starts flashing a red error light, but everything else returns successful. I can run this same code on my laser printer and everything works fine. How can I see what is causing the error on my label printer? Code: public class Test { private Font printFont; private List<string> _documentLinesToPrint = new List<string>(); public void Run() { _documentLinesToPrint.Add("Test1"); _documentLinesToPrint.Add("Test2"); printFont = new Font("Arial", 10); var pd = new PrintDocument(); pd.DefaultPageSettings.Margins = new Margins(25, 25, 25, 25); pd.DefaultPageSettings.PaperSize = new PaperSize("Label", 400, 237); var printerSettings = new System.Drawing.Printing.PrinterSettings(); printerSettings.PrinterName ="Brother QL-570 LE"; pd.PrinterSettings = printerSettings; pd.PrinterSettings.Copies = 1; pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage); pd.Print(); } // The PrintPage event is raised for each page to be printed. private void pd_PrintPage(object sender, PrintPageEventArgs ev) { float linesPerPage = 0; float yPos = 0; int count = 0; float leftMargin = ev.MarginBounds.Left; float topMargin = ev.MarginBounds.Top; string line = null; // Calculate the number of lines per page. linesPerPage = ev.MarginBounds.Height / printFont.GetHeight(ev.Graphics); // Print each line of the file. while ((count < linesPerPage) && (count < _documentLinesToPrint.Count)) { line = _documentLinesToPrint[count]; yPos = topMargin + (count * printFont.GetHeight(ev.Graphics)); ev.Graphics.DrawString(line, printFont, Brushes.Black, leftMargin, yPos, new StringFormat()); line = null; count++; } // If more lines exist, print another page. if (line != null) ev.HasMorePages = true; else ev.HasMorePages = false; } }

• Use a System.Drawing.Printing.PrintDocument to generate a PDF in memory

  - by MarkB29

  Does anyone know if the following is possible and if so what the best way of doing it is for free? I am generating a PrintDocument in a project I am currently working on and displaying a print dialog box so a user can choose which printer they want to use etc. The is currently a windows form application and if a user wants to print to a PDF they can select to print to CutePDF or something similar. However I am now putting a ASP.Net web frontend on the application and want to use the same code to generate the PrintDocument but want to print it to a PDF on the fly and serve it up via the Response stream in the format of a PDF download. So my question is....How can I use the current PrintDocument and generate a PDF in memory from it?? Thanks

• How can I process an image in .NET for a full-page print with a quality like Windows Photo Gallery d

  - by Triynko

  I'm writing a printing routing in C#, using the .NET PrintDocument class, handling the OnPrintPage event. I've managed to maximize the margins and print the Image in landscape mode, but it simply does not look as good as when I print the same image file from Windows Photo Gallery (formerly Windows Picture and Fax Viewer), the default image preview program in Windows Vista. I noticed an option there for selecting "Sharpen Image for Printing", but what does that do? I've thought about printing copies of the image from Windows Photo Gallery first, then sending the sheets through the printer a second time to print the custom overlays I need, but it's hard to make it line up every time, since the printer sucks the sheet in without the kind of precision I need... so I really need to do ALL the drawing commands within C#, including the image. Does anyone know how to perform pre-processing on the bitmap so that it prints as nicely as Windows Photo Gallery does it? Are there any simple print drivers that can intercept Photo Gallery printing output as a standard image file (bmp, png, etc.) that can be read by the .NET Image class? I'm all for creativity here.

  - by indira prasad

  I want the "default printer name" on the client's computer to print the Crystal ReportViewer Content My Code : printDocument = new System.Drawing.Printing.PrintDocument(); int nCopy = printDocument.PrinterSettings.Copies; int sPage = printDocument.PrinterSettings.FromPage; int ePage = printDocument.PrinterSettings.ToPage; string PrinterName = printDocument.PrinterSettings.PrinterName; rpt = (ReportDocument)Session["Report"]; rpt.PrintOptions.PrinterName = PrinterName; rpt.PrintToPrinter(nCopy, false, sPage, ePage); It is working fine locally but when I host the Application in IIS, that printer name it is taking default 'Microsoft XPS Document Writer' . thanks in advance.

• Print Preview Control used in a custom Print Preview Dialog.

  - by Kildareflare

  I have successfully implemented printing and print preview for my app using the PrintDocument, PrintDialog and PrintPreviewDialog classes of .NET. However my app uses a toolkit to improve the appearance of the standard .NET controls. There are versions of most .NET controls in the toolkit, but none for the Print controls. Therefore to ensure that the appearance of these controls matches the rest of the app I am creating a custom PrintPreviewDialog based on a toolkit form and embedding a .NET PrintPrewviewControl in it. My problem is that the PrintPreviewControl always shows "No pages to display". I had no trouble getting this to work using the .NET PrintPreviewDialog and cannot see what I am doing wrong. This is a .NET 2.0 PrintPreviewControl and so I know that I need to call InvalidatePreview() after assigning the PrintDocument. However it does not seem to matter where i place it, the PrintPage event handler never gets called... EDIT: I've just noticed that while the original PrintDocument m_printDocument shows a PrintPageHandler in its properties, the m_printPreviewControl.Document does not. Any ideas why it is being lost..? public class PrintEngine { ...rest of class... public PrintEngine() { m_printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage); } public void PrintPreview() { //ORIGINAL CODE USING .NET DIALOG WORK OK //PrintPreviewDialog dlg1 = new PrintPreviewDialog(); //dlg1.Document = m_printDoc; //PrepareImageForPrinting(); //dlg1.ShowDialog(); //CODE USING MY CUSTOM DIALOG DO NOT WORK? MyPrintPreviewDialog dlg2 = new MyPrintPreviewDialog(); dlg2.Document = m_printDoc; PrepareImageForPrinting(); //Creates the m_printImage List dlg2.ShowDialog(); } private void printDoc_PrintPage(object sender, PrintPageEventArgs e) { e.Graphics.DrawImage(m_printImages[m_currentPage], new Point(0, 0)); m_currentPage++; e.HasMorePages = m_currentPage < m_pagesHigh; } }//end PrintEngine class public class MyPrintPreviewDialog : KryptonForm { public PrintDocument Document { get { return m_printPreviewControl.Document; } set { m_printPreviewControl.Document = value; m_printPreviewControl.InvalidatePreview(); } } public MyPrintPreviewDialog() { InitializeComponent(); m_printPreviewControl = new PrintPreviewControl(); m_printPreviewControl.StartPage = 0; } private void MyPrintPreviewDialog_Load(object sender, EventArgs e) { m_printPreviewControl.Document.DefaultPageSettings = new PageSettings(); m_printPreviewControl.Document.PrinterSettings = new PrinterSettings(); m_printPreviewControl.InvalidatePreview(); } }//end MyPrintPreviewDialog class

  I need to print a large image collection of pictures. If I use something like: printDocument.PrintPage += OnPrintPage; printDocument.Print(); my printing task size in printer queue takes more than 1 GB! Can anyone suggest how can I print the images one by one. Maybe some event like PrintJobIsFinished is available?

• Send document to printer from web page

  - by FiveTools

  I have a webpage that activates a print job on a printer. This works in the localhost environment but does not work when the application is deployed to the webserver. I'm using the PrintDocument class from the .net System.Drawing.Print namespace. I'm now assuming the printer has to be available to the application on the remote server? Any suggestions on how I would get this to work? PrintDocument pd = new PrintDocument(); PaperSource ps = new PaperSource(); pd.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("Custom", 1180, 850); pd.PrintPage += new PrintPageEventHandler (this.pd_PrintPage); // Set your printer's name. Obtain from // System's Printer Dialog Box. pd.PrinterSettings.PrinterName = "Okidata ML 321 Turbo/D (IBM)"; //PrintPreviewDialog dlgPrintPvw = new PrintPreviewDialog(); //dlgPrintPvw.Document = pd; //dlgPrintPvw.Focus(); //dlgPrintPvw.ShowDialog(); pd.Print();

• How do I print an HTML document from a web service?

  - by Chris Marasti-Georg

  I want to print HTML from a C# web service. The Web Browser control is overkill, and does not function well in a service-environment, nor does it function well on a system with very tight security constraints. Is there any sort of free .NET library that will support the printing of a basic HTML page? Here is the code I have so far, that is not running properly. public void PrintThing(string document) { if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA) { Thread thread = new Thread((ThreadStart) delegate { PrintDocument(document); }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); } else { PrintDocument(document); } } protected void PrintDocument(string document) { WebBrowser browser = new WebBrowser(); browser.DocumentText = document; while (browser.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); } browser.Print(); } This works fine when called from UI-type threads, but nothing happens when called from a service-type thread. Changing Print() to ShowPrintPreviewDialog() yields the following IE script error: Error: 'dialogArguments.___IE_PrintType' is null or not an object URL: res://ieframe.dll/preview.dlg And a small empty print preview dialog appears.

• Automatically Word-Wrapping Text To A Print Page?

  - by sooprise

  I have some code that prints a string, but if the string is say: "Blah blah blah"... and there are no line breaks, the text occupies a single line. I would like to be able to shape the string so it word wraps to the dimensions of the paper. private void PrintIt(){ PrintDocument document = new PrintDocument(); document.PrintPage += (sender, e) => Document_PrintText(e, inputString); document.Print(); } static private void Document_PrintText(PrintPageEventArgs e, string inputString) { e.Graphics.DrawString(inputString, new Font("Courier New", 12), Brushes.Black, 0, 0); } I suppose I could figure out the length of a character, and wrap the text manually, but if there is a built in way to do this, I'd rather do that. Thanks!

• Printing in Silverlight 4

  - by Number8

  Hello, We have an application structured roughly like this: <Grid x:Name="LayoutRoot"> <ScrollViewer> <Canvas x:Name="canvas"> <StackPanel> < Button /><Slider /><Button /></StackPanel> <custom:Blob /> <custom:Blob /> <custom:Blob /> </Canvas> </ScrollViewer> </Grid> Each Blob consists of 1 or more rectangles, lines, and text boxes; they are positioned anywhere on the canvas. If I print the document using the LayoutRoot: PrintDocument pd = new PrintDocument(); pd += (s, pe) => { pe.PageVisual = LayoutRoot; }; pd.Print("Blobs"); ... it is like a print-screen -- the scrollbars, the sliders, the blobs that are visible -- are printed. If I set PageVisual = canvas, nothing is printed. How can I get all the blob objects, and just those objects, to print? Do I need to copy them into another container, and give that container to PageVisual? Can I use a ViewBox to make sure they all fit on one page? Thanks for any pointers....

• Printing problem in Silverlight 4.0 RC - loading images in code behind

  - by Jacek Ciereszko

  Few days ago I faced a problem with printing in new Silverlight 4 RC. When you try to dynamically load image (in code behind) and print it, it doesn't work. Paper sheet is blank. Problem XAML file: <Image x:Name="image" Stretch="None" /> XAML.cs: image.Source = new BitmapImage(new Uri(imageUri, UriKind.RelativeOrAbsolute));  Print: var pd = new PrintDocument();   pd.PrintPage += (s, args) =>     {       args.PageVisual = image;     };   pd.Print(); Result: Blank paper.   Solution What you need to do, is forced Silverlight engine to load that image before printing start. To accomplish that I proposed simply checking PixelWith value. Your code will ask about PixelWidth of image so it will have to be loaded. XAML.cs: BitmapImage bImage = new BitmapImage(new Uri(imageUri, UriKind.RelativeOrAbsolute)); image.Source = bImage; InitControl(imageUri, movieUri, isLeft); int w = bImage.PixelWidth; int h = bImage.PixelHeight;   DONE!   Jacek Ciereszko

• How to copy a System.Drawing.Graphics over another Graphics?

  - by Simon T.

  We got some code that implement printing using Printdocument and it does all the drawing directly on the Graphics object received in the PrintEventArgs. It would be more convenient if the code doing the drawing used another canvas and we would add this canvas to the PrintEventArgs Graphics after. Since the code already depends on the Graphics object I need a canvas with this object. I also need a way to copy the canvas onto the PrintEventArgs Graphics. I can create a Graphicsfrom an Image but as far as I know it needs to be stored on the disk. Any suggestions?

• WinForms prints to default printer even if it's not available/connected

  - by Valentein

  How can I determine if printer is connected? Typically this application prints to the default printer but in some cases that printer may not be available. If so I don't want the job sent to it's queue but rather printed to another available printer. I understand the PinterSettings.InstalledPrinters property. Does PrintDocument.PrinterSettings.IsValid return false if a printer is not available? Does WPF provide this kind of functionality? My problem is different than Printing problem in C# windows app - Always prints to default printer

• How do I send a PDF in a MemoryStream to the printer in .Net?

  - by Ryan ONeill

  I have a PDF created in memory using iTextSharp and contained in a MemoryStream. I now need to translate that MemoryStream PDF into something the printer understands. I've used Report Server in the past to render the pages to the printer format but I cant use it for this project. Is there a native .Net way of doing this? For example, GhostScript would be OK if it was a .Net assembly but I don't want to bundle any non .Net stuff along with my installer. The PrintDocument class in .Net is great for sending content to the printer but I still need to translate it from a PDF stream into GDI at the page level. Any good hints? Thanks in advance Ryan

• Generating PDF files from .NET by using standard .NET GDI printing classes

  - by Philippe Leybaert

  I'm looking for a way to generate PDF files using the standard PrintDocument and Graphics (GDI) classes in .NET. As far as I know, the only way to do that is by printing to a PDF printer. The problem is that a PDF printer driver always asks for a filename, but I need to control the filename from my code. Using a PDF library like PDFSharp or DynamicPDF is not an option, because they all provide their own API for generating PDF files. I need this for an internal application, so dependencies are not a problem. My question is simple: is there a way to control a printer driver (Adobe Acrobat, PDFCreator, ...) in such a way that a filename can be specified and the user is not prompted for anything?
