The WCPP client utility
Each client machine that wants to print locally from ASP.NET Core websites by using the WebClientPrint solution will require to install a very small utility called WebClientPrint Processor (WCPP).
WCPP is a lightweight native app (without any dependencies) that processes all the Client Print Jobs generated by the WebClientPrint server-side component.
WCPP is great because it is a native app that does not require the client to install any other dependencies or frameworks (like Java, .NET, ActiveX, Silverlight, Flash, etc.) and runs on Windows, Linux & Mac! You can keep your current enterprise hardware, save money and start porting your systems to ASP.NET Core web apps with your current infrastructure.
The client machine requirements are:
- OS: Windows 98, 2000, ME, XP, Vista, Windows 7, Windows 8.x (Desktop-mode), Windows 10
- BROWSER: Internet Explorer 6 or greater (IE10/11 in Desktop Mode), Microsoft Edge, Mozilla Firefox 2.0 or greater, Google Chrome 11 or greater, Opera 9.0 or greater, Safari 3.0 or greater
- OS: Debian 6 or greater (GNOME), Ubuntu 10.04 or greater (Unity/GNOME), Linux Mint 7 or greater (GNOME), Fedora 11 or greater (GNOME), CentOS 5.3 or greater (GNOME)
- BROWSER: Mozilla Firefox shipped with the OS or latest version, Google Chrome latest version
- OS: Mac OS X 10.5 (Leopard) or greater / Intel
- BROWSER: Safari shipped with the OS or latest version, Mozilla Firefox latest version, Google Chrome latest version
How WCPP works?
WCPP is launched from the client machine each time the user that interacts with your website takes an action which invokes the jsWebClientPrint.print() (usually when clicking on a Print button or anchor you provide in your website)
When launched, WCPP makes HTTP GET requests to your ASP.NET Core Websites. This request will be handled by a Controller which after processing the printing request, it will create and return a Client Print Job. Please refer to the WebClientPrint Server Component
Proxy Server Environments
If the user requires to passthrough a Proxy Server to get access to your website, then the WCPP Utility needs to be specified with the Proxy Settings. To do this, the following commands need to be executed from the Command Line/Terminal in the Client Machine
Specifying Proxy Settings
[WCPP Install Folder]/wcpp -proxyHost:10.0.0.20 -proxyPort:8080 -proxyUser:TheUser -proxyPass:ABC123
Delete Proxy Settings
[WCPP Install Folder]/wcpp -proxyHost:delete -proxyPort:delete -proxyUser:delete -proxyPass:delete
