How can I send a file document to the printer and have it print

Question

Here s the basic premise   My user clicks some gizmos and a PDF file is spit out to his desktop  Is there some way for me to send this file to the printer queue and have it print to the locally connected printer   string filePath    filepathisalreadysethere   SendToPrinter filePath     Something like this    He will do this process many times  For each student in a classroom he has to print a small report card  So I generate a PDF for each student  and I d like to automate the printing process instead of having the user generated pdf  print  generate pdf  print  generate pdf  print   Any suggestions on how to approach this  I m running on Windows XP with Windows Forms  NET 4   I ve found this StackOverflow question where the accepted answer suggests      Once you have created your files  you   can print them via a command line  you   can using the Command class found in   the System Diagnostics namespace for   that    How would I accomplish this

I know the tag says Windows Forms    but  if anyone is interested in a WPF application method  System Printing works like a charm   var file   File ReadAllBytes pdfFilePath   var printQueue   LocalPrintServer GetDefaultPrintQueue     using  var job   printQueue AddJob    using  var stream   job JobStream        stream Write file  0  file Length       Just remember to include System Printing reference  if it s not already included    Now  this method does not play well with ASP NET or Windows Service   It should not be used with Windows Forms  as it has System Drawing Printing   I don t have a single issue with my PDF printing using the above code   I should mention  however  that if your printer does not support Direct Print for PDF file format  you re out of luck with this method

This is a slightly modified solution  The Process will be killed when it was idle for at least 1 second  Maybe you should add a timeof of X seconds and call the function from a separate thread   private void SendToPrinter       ProcessStartInfo info   new ProcessStartInfo      info Verb    print     info FileName     c  output pdf     info CreateNoWindow   true    info WindowStyle   ProcessWindowStyle Hidden     Process p   new Process      p StartInfo   info    p Start       long ticks   -1    while  ticks    p TotalProcessorTime Ticks          ticks   p TotalProcessorTime Ticks      Thread Sleep 1000          if  false    p CloseMainWindow        p Kill

this is a late answer  but you could also use the File Copy method of the System IO namespace top send a file to the printer   System IO File Copy filename  printerName     This works fine

You can use the DevExpress PdfDocumentProcessor Print PdfPrinterSettings  Method   public void Print string pdfFilePath          if   File Exists pdfFilePath             throw new FileNotFoundException  No such file exists    pdfFilePath             Create a Pdf Document Processor instance and load a PDF into it        PdfDocumentProcessor documentProcessor   new PdfDocumentProcessor          documentProcessor LoadDocument pdfFilePath          if  documentProcessor    null                    PrinterSettings settings   new PrinterSettings                 var paperSizes   settings PaperSizes Cast lt PaperSize gt    ToList                PaperSize sizeCustom   paperSizes FirstOrDefault lt PaperSize gt  size   gt  size Kind    PaperKind Custom      finding paper size            settings DefaultPageSettings PaperSize   new PaperSize  Label   400  600                 Print pdf           documentProcessor Print settings

You can tell Acrobat Reader to print the file using  as someone s already mentioned here  the  print  verb  You will need to close Acrobat Reader programmatically after that  too   private void SendToPrinter        ProcessStartInfo info   new ProcessStartInfo       info Verb    print      info FileName     c  output pdf      info CreateNoWindow   true     info WindowStyle   ProcessWindowStyle Hidden      Process p   new Process       p StartInfo   info     p Start        p WaitForInputIdle       System Threading Thread Sleep 3000      if  false    p CloseMainWindow          p Kill        This opens Acrobat Reader and tells it to send the PDF to the default printer  and then shuts down Acrobat after three seconds   If you are willing to ship other products with your application then you could use GhostScript  free   or a command-line PDF printer such as http   www commandlinepdf com   commercial    Note  the sample code opens the PDF in the application current registered to print PDFs  which is the Adobe Acrobat Reader on most people s machines  However  it is possible that they use a different PDF viewer such as Foxit  http   www foxitsoftware com pdf reader    The sample code should still work  though

I know Edwin answered it above but his only prints one document  I use this code to print all files from a given directory   public void PrintAllFiles         System Diagnostics ProcessStartInfo info   new System Diagnostics ProcessStartInfo        info Verb    print       System Diagnostics Process p   new System Diagnostics Process          Load Files in Selected Folder     string   allFiles   System IO Directory GetFiles Directory       foreach  string file in allFiles                info FileName    file          info CreateNoWindow   true          info WindowStyle   System Diagnostics ProcessWindowStyle Hidden           p StartInfo   info          p Start                p Kill    Can Create A Kill Statement Here    but I found I don t need one     MessageBox Show  Print Complete        It essentually cycles through each file in the given directory variable Directory -   for me it was   C  Users Owner Documents SalesVaultTesting   and prints off those files to your default printer

The following code snippet is an adaptation of Kendall Bennett s code for printing pdf files using the PdfiumViewer library  The main difference is that a Stream is used rather than a file    public bool PrintPDF      string printer      string paperName      int copies  Stream stream                        try                                  Create the printer settings for our printer                 var printerSettings   new PrinterSettings                                       PrinterName   printer                      Copies    short copies                                     Create our page settings for the paper size selected             var pageSettings   new PageSettings printerSettings                                Margins   new Margins 0  0  0  0                              foreach  PaperSize paperSize in printerSettings PaperSizes                                if  paperSize PaperName    paperName                                        pageSettings PaperSize   paperSize                      break                                                  Now print the PDF document             using  var document   PdfiumViewer PdfDocument Load stream                                 using  var printDocument   document CreatePrintDocument                                          printDocument PrinterSettings   printerSettings                      printDocument DefaultPageSettings   pageSettings                      printDocument PrintController   new StandardPrintController                        printDocument Print                                                return true                    catch  System Exception e                        return false                    In my case I am generating the PDF file using a library called PdfSharp and then saving the document to a Stream like so           PdfDocument pdf   PdfGenerator GeneratePdf printRequest html  PageSize A4           pdf AddPage             MemoryStream stream   new MemoryStream            pdf Save stream           MemoryStream stream2   new MemoryStream stream ToArray       One thing that I want to point out that might be helpful to other developers is that I had to install the 32 bit version of the pdfuim native dll in order for the printing to work even though I am running Windows 10 64 bit  I installed the following two NuGet packages using the NuGet package manager in Visual Studio    PdfiumViewer PdfiumViewer Native x86 v8-xfa

Adding a new answer to this as the question of printing PDF s in  net has been around for a long time and most of the answers pre-date the Google Pdfium library  which now has a  net wrapper  For me I was researching this problem myself and kept coming up blank  trying to do hacky solutions like spawning Acrobat or other PDF readers  or running into commercial libraries that are expensive and have not very compatible licensing terms  But the Google Pdfium library and the PdfiumViewer  net wrapper are Open Source so are a great solution for a lot of developers  myself included  PdfiumViewer is licensed under the Apache 2 0 license   You can get the NuGet package here   https   www nuget org packages PdfiumViewer   and you can find the source code here   https   github com pvginkel PdfiumViewer  Here is some simple code that will silently print any number of copies of a PDF file from it s filename  You can load PDF s from a stream also  which is how we normally do it   and you can easily figure that out looking at the code or examples  There is also a WinForm PDF file view so you can also render the PDF files into a view or do print preview on them  For us I simply needed a way to silently print the PDF file to a specific printer on demand   public bool PrintPDF      string printer      string paperName      string filename      int copies        try              Create the printer settings for our printer         var printerSettings   new PrinterSettings               PrinterName   printer              Copies    short copies                         Create our page settings for the paper size selected         var pageSettings   new PageSettings printerSettings                Margins   new Margins 0  0  0  0                      foreach  PaperSize paperSize in printerSettings PaperSizes                if  paperSize PaperName    paperName                    pageSettings PaperSize   paperSize                  break                                      Now print the PDF document         using  var document   PdfDocument Load filename                 using  var printDocument   document CreatePrintDocument                      printDocument PrinterSettings   printerSettings                  printDocument DefaultPageSettings   pageSettings                  printDocument PrintController   new StandardPrintController                    printDocument Print                                    return true        catch           return false
