*
* ~ HOW TO USE
* ~~~~~~~~~~~~
*
* 1. First of all copy the file called "libprint.js" to a suitable folder.
* 2. Links the "libprint.js" file to the HEAD section of the HTML source as shown below:
* eg:
*
*
* 3. Then calls the "shn_print_init()" function at your prefered location in the HTML source
* eg:
* XForm
*
* 4. Clicks on the link "XForm" to get the generated output and then navigate through File >> Print in the web browser to print the page.
*
* 5. Once the user click on the XForm and needs to switched on to the normal view just click on F5 key or refresh the page
*
*
*
*
* ~ LIMITATIONS
* ~~~~~~~~~~~~~
*
* 1. Currently library doesn't give the facility to the user to change the generated field layout structure dynamically except for the date layout.
*
* 2. The library will only function in its maximum accuracy when the system is used with en_US locale, with other locales it only generats a form with a basic layout
*
* 3. This version s the generated form only to match a A4 page.
*
* 4. Currently the library renders the page accurately with FF2, Opera 8 and IE6
*
* 5. Element extraction process get limits to following parameters:
* ~ The form elements should resides within the given DIV element having the CLASS attribute "form-container", but you can change the class attribute name provided that you change the JavaScript library(libprint.js) appropriatly ( in the library search and finds the "shn_print_create_basic_elements_layout()" function and change the "form-container" value to the value used in your HTML source).
* ~ The library supports the extaction of required elements only if the elements are structured as shown below.
*
*
*
*
*
*
*
*
* ~ Accuracy of the functionality fails if the elements are nested within several fieldset elements as shown below.
