1) Is there anyway i can provide a print functionality in user Input Task so tha

Just to expand a little bit more on what Stefan mentions on point #1 I created an example a while ago available for download here: forum.appian.com/.../15487
The model is called Print Form under Process Models - Forum and the JS is called printFunctionality.js under Default Community > Temporary Documents Knowledge Center > Temporary Documents>JS libraries


Here is the explanation: You can window.print() to print the form. I can think of two approaches. One would be to add that JS to an image (using the image component) and the other one is adding it to a button.

My suggestion would be to use the first approach; the image. You can achieve this effect by using the following function:

function addPrintFunctionalityToImage(imageId){
var originalHTML = $("#fd_component_"+ window.FormDesigner.runtimeNamespace+ imageId +" div.fields").html();
var newHTML = "<a href='#'>" + originalHTML + "</a>";
$("#fd_component_"+ window.FormDesigner.runtimeNamespace+ imageId +" div.fields").html(newHTML)
$("#fd_component_"+ window.FormDesigner.runtimeNamespace+ imageId +" img").click(function(){window.print();});
}

Let me explain what we're doing here. This logic is to add the window.print() to the click event of the image but also to add an empty link in order to display the cursos as if this image was a link (little hand). I am using JQuery (already used by Appian, so no need to deploy anything extra) to retrieve the original HTML of the div where the image is rendered and I just enclose it in an empty link, then I add the JS to click event of the image.

For the second approach the drawback is that the button will show the print window but after the form is printed it will submit the form, which is expected because buttons are submit buttons all the time.

If you don't mind submitting the form after printing it this function adds that to the button:

function addPrintFunctionalityToButton(buttonId){
var buttonConfig = window.Build.util.getComponentContainer(buttonId,window.FormDesigner.runtimeNamespace);
var clickFunction = function(){window.print();};
buttonConfig[0].firstChild.onclick = clickFunction;
}

For any of these functions you have to call them in the load event of your form sending either the image id or button (from the forms designer)
