How to Send a File Document to the Printer and Have It Print

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

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.

How can I send docx and pdf file to printer?

Your example above is taking a binary file format and trying to print it using a method that uses plain text, which will not work. You have a few options on how you could approach this.

1. Some printers allow you to submit various file types directly to them over a protocol like FTP. And example of this can be seen here. This method works great in enterprise environments which have business printers but is limited to the file types supported by each printer, and each printer's unique requirements.
2. For some formats, you can use third-party libraries like iText in your C# code to handle the actual printing. This option gives you a ton of control over the formatting, with the overhead of having to maintain additional code for every file type you wish to support.
3. You can also use the example code posted here to utilize already installed applications. In this example, it takes advantage of the Print verb made available by Adobe Acrobat, Word, etc. You'll need to make sure the applications have their defaults and surface the correct verb (which typically correlates with the context menu when right-clicking on a file name). This method is probably the most straight-forward option to handle files as-is.

Send Multiple Documents To Printer

question subject is look like wrong...
answer;

var filenames = Directory.EnumerateFiles(@"c:\targetImagePath", "*.*", SearchOption.AllDirectories)
                        .Where(s => s.EndsWith(".gif") || s.EndsWith(".jpg") || s.EndsWith(".bmp"));
foreach (var filename in filenames)
{
    //use filename
}

Send file to printer, nothing is printed

You need to add a print page event handler that outputs your data to the printer.

If strFileName is the file name containing the data, then

• Open the file in the code above saving the streamreader in a global
  instance var.
• Add the page event handler
• Close the stream at exit

I think that this example in MSDN fits exactly

If you look at the documentation in MSDN about DocumentName property you will find this statement

The DocumentName property does not specify the file to print.  
Rather, you specify the output to print by handling the PrintPage event.  
For an example, see the PrintDocument class overview.

ASP.NET: How to send file from database to printer?

Do you want to print to a Printer attached to the Server, or attached to the client?

If you want to print on the Client, you won't have much chance. For HTML Content, maybe some JavaScript or Flash could trigger the Print Dialog (not sure), but if it's a File that has to be opened in a third party application (i.e. PDF, DOC, XLS etc.), you're out of luck.

If it's an internal Network, you could possibly create a Desktop Application that is installed on every Client's PC that then triggers the Print.

If it is a Printer Attached to the Server, you can use the standard .net facilities for Printing, although you again may have to work around situations where you are trying to print PDF/DOC/XLS etc., because then you need to use Automation (either COM or something like SendKeys), which will cause you headaches on a Server.

So in Short: Not much you can do with only ASP.net at your disposal.

Send document to printer with C#

The key phrase in that question is 'web application'.

In a normal web app using only HTML+Javascript over HTTP, you can't just send a document directly to a printer. That's one of the reasons web browsers exist, and without that functionality everyone's printer would collect the same kind of junk that a public fax machine does.

So you need some kind of work-around. One option is to build on a common plug-in, like flash, silverlight, java applet, or even something like greasemonkey. Another is a custom plug-in, like a hosted winforms control or custom browser extension.

You are very fortunate, in that it looks like you have complete control (or knowlege of) the deployment environment, and that this environment if fairly homogenous. This means you have an additional option that others have started to explore. If you can install all of the printers in your environment to the web server, then it's fairly easy using the built-in .Net printer classes (in the System.Drawing.Printing namespace) to list out those printer, either show them to the user so they can pick or keep some kind of IP to Printer mapping table, and then print directly to that printer from your web app. Note that this scheme may require your app to run at a higher level of trust than would otherwise be required.

Now it comes to actually printing your PDF's and word documents. For acrobat, check this link:

http://support.adobe.com/devsup/devsup.nsf/docs/52080.htm (Wayback machine)

Note that it's a little dated, but I believe the concept is still valid. You'll have to experiment some to make sure it works as expected.

For Word, I'm not normally a fan of Office interop/automation in a web app. But in this case you're not editing any documents: just loading it up long enough to print. And the fact that you're relying on another scarce resource (the printers) should keep this from scaling beyond what your web server could cope with. So you may have a rare case where Office automation in a web project makes sense.

.net c# sending a file to the printer from a console application

After comparing different libraries for printing (and pdf manipulation) we went for Gembox.Pdf to meet the requirements. This allows us to print pdf, png, jpg and more from a windows service.
