How does the Javascript print function work? Can I create a document using javascript and print it off?

wish help you to fix your issue Print() is a method on the window object. If you create a document in a window using javascript, then call print on that window object, it should work.
code :
<script type="text/javascript">
    var myWindow = window.open('','','width=200,height=100')
    myWindow.document.write("This is 'myWindow'")
    myWindow.print();
</script>

How can I print an HTML document from C# or javascript without user confirmation?

this will help From any major browser -- I'm pretty sure you can't.
You could create a WinForm app that has a WebBrowser control embedded in it and print from there without user confirmation (if I remember correctly, there is a Print method off the object).

Javascript: define, select, and print context of any clicked node from an html document?

wish helps you So, eventually, I worked out a solution. It isn't pretty and I am sure there are more elegant/efficient ways of achieving the same results. But this got me what I needed (for now...).
Essentially, I needed to break the process down into steps and add if/else if/else statements to catch possible exceptions at each stage while defining which elements I wanted and which ones I didn't want. This solution relies on only elements that are to be included in the context having the @id attribute.
code :
function getContext() {
var el = document.getElementById(id); // THIS GETS THE CLICKED <a> ELEMENT
var form = el.outerHTML;
var el_plus_1; // THIS CHECKS IF THERE IS A NEXT SIBLING ELEMENT AND SELECTS IT IF SO 
if (el == el.parentNode.lastElementChild) {
    el_plus_1 = "";
    }
    else if (el.nextElementSibling == null) {
    el_plus_1 = "";
    }
    else {el_plus_1 = el.nextElementSibling}
var el_minus_1; // THIS CHECKS IF THERE IS A PREV SIBLING ELEMENT AND SELECTS IT IF SO 
if (el == el.parentNode.firstElementChild) {
    el_minus_1 = "";    
    }
    if (el.previousElementSibling == null) {
    el_minus_1 = "";
    }
    else {el_minus_1 = el.previousElementSibling}
var el_plus_2; // THIS CHECKS IF THERE IS A NEXT+1 SIBLING ELEMENT AND SELECTS IT IF SO 
if (el == el.parentNode.lastElementChild) {
    el_plus_2 = "";
    }
    else if (el.nextElementSibling == el.parentNode.lastElementChild) {
    el_plus_2 = ""; 
    }
    else if (el.nextElementSibling.nextElementSibling == null) {
    el_plus_2 = "";
    }
    else {el_plus_2 = el.nextElementSibling.nextElementSibling}
var el_minus_2; // THIS CHECKS IF THERE IS A PREV-1 SIBLING ELEMENT AND SELECTS IT IF SO 
if (el == el.parentNode.firstElementChild) {
    el_minus_2 = "";    
    }
    else if (el.previousElementSibling == el.parentNode.firstElementChild) {
    el_minus_2 = "";    
    }
    else if (el.previousElementSibling.previousElementSibling == null) {
    el_minus_2 = "";
    }
    else {el_minus_2 = el.previousElementSibling.previousElementSibling}
var el_plus_1Id; // THIS GETS THE ID FOR NEXT, IF IT HAS AN ID
    if (el_plus_1.id == null) {
    el_plus_1Id = "";   
    }
    else {el_plus_1Id = el_plus_1.id}
var el_minus_1Id; // THIS GETS THE ID FOR PREV, IF IT HAS AN ID
    if (el_minus_1.id == null) {
    el_minus_1Id = "";  
    }
    else {el_minus_1Id = el_minus_1.id}
var el_plus_2Id; // THIS GETS THE ID FOR NEXT+1, IF IT HAS AN ID
    if (el_plus_2.id == null) {
    el_plus_2Id = "";   
    }
    else {el_plus_2Id = el_plus_2.id}
var el_minus_2Id; // THIS GETS THE ID FOR PREV-1, IF IT HAS AN ID
    if (el_minus_2.id == null) {
    el_minus_2Id = "";  
    }
    else {el_minus_2Id = el_minus_2.id}
var el_plus_1node; // THIS SELECTS THE NEXT DESIRED ELEMENT AND ALL CHILDREN, IF IT HAS AN ID. IF NOT, AN EMPTY STRING IS RETURNED INSTEAD.
    if (el_plus_1Id === "") {
    el_plus_1node = "";
    }
    else {el_plus_1node = document.getElementById(el_plus_1Id).outerHTML}
var el_minus_1node; // THIS SELECTS THE PREV DESIRED ELEMENT AND ALL CHILDREN, IF IT HAS AN ID. IF NOT, AN EMPTY STRING IS RETURNED INSTEAD.
    if (el_minus_1Id === "") {
    el_minus_1node = "";
    }
    else {el_minus_1node = document.getElementById(el_minus_1Id).outerHTML}
var el_plus_2node; // THIS SELECTS THE NEXT+1 DESIRED ELEMENT AND ALL CHILDREN, IF IT HAS AN ID. IF NOT, AN EMPTY STRING IS RETURNED INSTEAD.
    if (el_plus_2Id === "") {
    el_plus_2node = "";
    }
    else {el_plus_2node = document.getElementById(el_plus_2Id).outerHTML}
var el_minus_2node; // THIS SELECTS THE PREV-1 DESIRED ELEMENT AND ALL CHILDREN, IF IT HAS AN ID. IF NOT, AN EMPTY STRING IS RETURNED INSTEAD.
    if (el_minus_2Id === "") {
    el_minus_2node = "";
    }
    else {el_minus_2node = document.getElementById(el_minus_2Id).outerHTML}
var context = el_minus_2.concat(' ', el_minus_1, ' ', '<b>' + form + '</b>', ' ', el_plus_1, ' ', el_plus_2); 
// THIS SLOTS ALL THE SELECTED CONTEXT NODES TOGETHER, RETURNING EITHER THE NODES AND CHILD ELEMENTS OR EMPTY/INVISIBLE STRINGS.
