How to directly Print Word docs without Preview or Printer Dialog from ASP.NET
How to directly Print Word docs without Preview or Printer Dialog from ASP.NET
In this walkthrough, you'll learn how to print any MS Word document (*.doc; *.docx) from an ASP.NET website to the client printer without displaying a
print dialog. You'll be able to print the Word doc to the Default client printer as well as to any other installed printer at the client machine. This
solution works with any browser on Windows OS like IE (6 or later), Chrome, Firefox, Opera & Safari!
Requirements
Development/Server-side
- WebClientPrint 2.0 for ASP.NET (or greater)
- ASP.NET 3.5 (or greater)
- Visual Studio 2010 / VWD 2010 (or greater)
- jQuery 1.4.1 (or greater)
Client-side
- WebClientPrint Processor 2.0 for Windows (WCPP) - Part of WebClientPrint Solution
- Microsoft Word
Follow up these steps
- Download & install WebClientPrint for ASP.NET
- Open Visual Studio and create a new ASP.NET 3.5 Website naming it PrintWordDocSample
- Add a reference to Neodynamic.SDK.WebClientPrint.dll to your project
- Open your web.config file and add the following entries:
<system.web>
...
<httpHandlers>
...
<add verb="*" path="wcp.axd" type="Neodynamic.SDK.Web.WebClientPrint, Neodynamic.SDK.WebClientPrint"/>
...
</httpHandlers>
...
</system.web>
<system.webServer>
...
<handlers>
...
<add name="WCP" verb="*" path="wcp.axd" type="Neodynamic.SDK.Web.WebClientPrint, Neodynamic.SDK.WebClientPrint"/>
...
</handlers>
...
</system.webServer>
- Open the default.aspx page and paste the following markup. The task of this page is to try to detect the WCPP and inform the user to install it if
it's missing.

<h3>#1 Install WebClientPrint Processor (WCPP)!</h3>
<p>
<strong>WCPP is a native Windows app (without any dependencies!)</strong> that handles all print jobs
generated by the <strong>WebClientPrint ASP.NET component</strong> at the server side. The WCPP
is in charge of the whole printing process and can be
installed on Windows 98, 2000, Me, XP, Vista, Windows 7 and Windows 8 (Desk-mode). It can print to Serial Port RS232 (e.g. COM1),
Parallel Port (e.g. LPT1), your Windows-Installed Printers (USB) and Network/IP Ethernet printers.
</p>
<p>
The <strong>WCPP</strong> utility <strong>is digitally-signed with a Windows Authenticode</strong> issued by <a
href="http://www.digicert.com">DigiCert, Inc.</a>. <strong>Install WCPP only if the <u>Publisher is Neodynamic
SRL</u></strong>, otherwise do not proceed. <br /><br />
<a href="http://www.neodynamic.com/downloads/wcpp20-installer.exe" target="_blank">Download and Install WCPP from Neodynamic
website</a><br />
</p>
<h3>#2 After installing WCPP...</h3>
<p>
<a href="PrintDoc.aspx">You can go and test the printing page</a>
</p>
</div>
</form>
<%-- Add Reference to jQuery at Google CDN --%>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<%-- Add Reference to spin.js (an animated spinner) --%>
<script src="http://fgnass.github.io/spin.js/dist/spin.min.js"></script>
<script type="text/javascript">
var wcppPingDelay_ms = 10000;

}
$(document).ready(function () {
<%-- Create the Spinner with options (http://fgnass.github.io/spin.js/) --%>
var spinner = new Spinner({
lines: 12,
length: 7,

}).spin($('#mySpinner')[0]);
});
</script>
<%-- WCPP detection script --%>
<%= Neodynamic.SDK.Web.WebClientPrint.CreateWcppDetectionScript() %>
</body>
</html>
- Finally, add a new ASPX page and name it PrintDoc.aspx (be sure to UNSELECT the "Place code in separate file" checkbox)
This page allows your user to print the Word doc file to local printers. The user is required to have MS Word installed to get this code working.
Please paste the following markup and code depending on your preferred language i.e. C# or VB on your PrintDoc.aspx file

- That's it! Run your website and test it. Click on Print Word Doc to print the doc file without preview. You can print it to the Default client
printer or you can get a list of the installed printers available at the client machine.
