jZebra To Print using the Browsers.

Pre-Requisites:-

1. Backend Web Server apace/tomacat/Node etc.
		*This demo uses Nodejs server.
2. Java greater than 1.5v.
	Get the java versions using this command from cmd:- java -version
	Or Update java to the latest versions.
3. Firefox with java plugins.(Strictly recommended)
	Test the browser for the java plugin or else update the browser with the java plugin.
4. Windows Or Linux

**Note:- Downloding or cloning this repository

    Just run these commnds one after one 
    cd folder_name 
    npm install 
    npm start

Getting the jzebra lib:-(If cloned this repository then no need to do down steps).

1. Download the jzebra library form the 
	https://code.google.com/p/jzebra/downloads/list
2. Extract it to the folder of your name.

Setting up the Thermal printer:-(Connect the printer using USB):-

Follow the steps from this link depending which OS you are using:-
	https://code.google.com/p/jzebra/wiki/TutorialWebApplet
*Note for Windows:- You get the driver cd with the printer, install the drivers for the printer you have. 			If drivers are not available then follow the documentation from above link.

Setting up the Backend server(Nodejs):- *Note:- You can setup your own backend server as you just have to server the required printing libs and files to the client.

1. Considering Nodejs and Express are installed on the machine, run this cmd
	express project_name
	cd project_name
	npm install
	npm start - just to check all is set by putting the http://localhost:3000 in firefox.
2. Here comes the actual flow:-
	A. Put all files in the public folder
		These file can be found under the extracted jzebra folder. 
			jzebra_extracted_folder/qz-print/dist/qz-print.jar
			jzebra_extracted_folder/qz-print/dist/qz-print_jnlp.jnlp
			jzebra_extracted_folder/qz-print/dist/js/*
	For Example:-
		app
			-public
				..
				javascripts
					---jzebra_extracted_folder/qz-print/dist/js/*
				qz-print.jar
				qz-print_jnlp.jnlp
			-views
				.html file which contains the print logic.(here print.html)
				print.html is sample.html found here jzebra_extracted_folder/qz-print/dist/sample.html
3. Then in main file of server ex:- app.js or server.js make the changes to serve the print.html page.

4. Then going to http://localhost:3000/ the firefox should ask for the blocked content permission. Allow the blocked content. If not then, update the java version installed on the machine.
5. Hence, the program should run.

** Amazing thing is that if the server gets disconnected then also POS print can be given. **For more info follow the jzebra code.google.com/p/jzebra
