JavaScript - How To Print On Pre-printed Reciept Using Dot Matrix Printer

Hey there guys, I'm working with an AJAX request that returns some stuff to print in 2 boxes. All working great, so I decided to make something fluffy, when I click a result in the AJAX request, he filters the clicked result, so you only see that clicked row. When clicked again, the old results will return. All working great.

Now, my problem, I wanted a checkbox after every row in the search results and when the user clicks twice on a result to filter it and than goes back to the old results to check the checkboxes again that were checked before filtering that component.

I made the functions and it didn't work till I put some alerts in, when the return function got some time to finish printing (like with the user had to click on OK in the alert) it worked. When I deleted the alerts, it didn't work again...

I searched on the internet, found a function to wait for an image to load or smth similar and I found some guys that used a function to wait for a specific time (1 sec for example) and that's not what I want. If I use a specific waittime it can still fail if the PC is slow, or whatever, it's just not nice coding.

So, is there something I can do so it waits till my AJAX request has been printed?


Thanks!

I've got a simple script that generates a button that sends to the printer when clicked. But a totally new thing to me is finding a way to update a "printed_unprinted" field in the database for that item. Anyone have experience with this?

Right now, I just have: Code:

<style type="text/css" media="print">
@page { size:8.5in 11in; margin: 1cm }
.printbutton {
  visibility: hidden;
  display: none;
}
</style>

<script>
document.write("<input type='button' " +
"onClick='window.print()' " +
"class='printbutton' " +
"value='Print This Page'/>");
</script>

I assume I could reference a php file? Just something quick like:

PHP Code:
<?php
include("include/conn.php");

$id = mysql_escape_string($_POST['printed']);

$query_update = "UPDATE tbl_registration SET reg_hardcopied = '1' WHERE reg_id = '$id'";
                     $dberror = "";
            $ret = mysql_query($query_update);
            if(!$ret){}
            else{
                //back to referrer

            }

hey there i was wondering if anyone knows how to get a print option button in a pop up window , i am using html with javascript to create a currency converter i have a button on my main page which opens up a popup window with information taken and totalled from the user input , i would like to be able to offer the option to print this window off .
code is

function open_win(){
myWindow=window.open('','','width=300,height=300');
myWindow.document.write("<p>Current sterling recieved</p>",sterling_total,"<p>Total commision recieved</p>",commision_total,"<p>Total Money Recieved</p>",running_total);
myWindow.focus();

}

Dear all,
I would like to use javascript that prints randomly one string to the string, from an array of predefined string.

How do you think I should start thinking that?

I'm working with the squeezebox modal.js implemented with Joomla! for my images in some extra fields. I'm trying to add a print button functionality in order to print the image within the lightbox.

Adding the button was fairly easy, I simply copied and pasted

this.closeBtn=(new Element("a",{id:"sbox-btn-close",href:"#"})).inject(this.win);

and made

this.printBtn=(new Element("a",{id:"sbox-btn-print",href:"#"})).inject(this.win);

I then made my print button png, went into the modal.css, added this:

#sbox-btn-print {
position: absolute;
width: 30px;
height: 30px;
right: 10px;
top: -15px;
background: url(../images/modal/print_btn.png) no-repeat center;
border: none;
}

And boom, print button, however making it work right is certainly not coming along as easy. I tried changing the href to
javascript:window.print()
but that just prints the contents of the browser, not the image in the box, no bueno. I then tried pushing the button functionality into a separate javascript function, but couldn't even get that far. I'm sure if I tweak it enough I can make it work, but I'm not all that great at programming within javascript. I'm fairly proficient with actionscript, php and css, I just don't know the syntax all involved here.

If anyone can point me in the right direction that would be appreciated. Sadly I can't simply switch it out with another lightbox that already has the option to print, as Joomla! K2 Extra Fields doesn't really give you that option. Help!

Hello!

I have a pretty straight forward question dealing with JQuery/Javascript (I'm pretty new to both, so the syntax is still escaping me). I have a javascript file that holds an array of objects inside of it (addresses to be exact) and I then need to take that array and call it to print into the Title attribute of a <li> after the list has been populated.

Below is the Javascript arrray:
Code:

var banner_data = [ "address1","address2","address3","address4"];
var obj = { one:"address1", two:"address2", three:"address3", four:"address4" }

And this is how it is being called in the HTML:
Code:

$('ul>li').each(function(){
      var $this = $(this); // current list item
      var idx = $this.index();
      var thisAddress = banner_data[idx]; 
	  $this.attr('title', thisAddress.append[4])
});

any thoughts? I have jQuery 1.7.1 installed, a fully valid html/css and a proper doctype (just to cover our bases haha)

This should be a simple fix.

I have a basic html form with some text input fields and a couple drop down selection lists.

Our employees print the form and include it with items they need our shipping department to ship for them.

The form uses the following verification script to ensure the required fields have been populated before the screen prints.

It works exactly as desired in Safari and Firefox. In Internet Explorer, however, the selections made in the drop down lists are reset to the default values on the printed form.

Before you respond with, "don't use Internet Explorer," you have to understand that Internet Explorer is our only corporate approved web browser because it is the only browser supported by some of our other "mission critical" third party web apps and because it can be more rigorously controlled using Group Policies than Safari, Firefox, Chrome, Opera, et al, can.

Any advice on how to make the form print without resetting the drop down list selections?

Code:

<script language="javascript">
    function verify() {
        var themessage = "You must provide the following information";
        if (document.shipment.SenderName.value == "") {
            themessage = themessage + ", Sender Name";
        }
        if (document.shipment.SenderEmail.value == "") {
            themessage = themessage + ", Sender Email";
        }
        if (document.shipment.Dept.value == "") {
            themessage = themessage + ", Department";
        }
        if (document.shipment.Contact.value == "") {
            themessage = themessage + ", Ship To Contact";
        }
        if (document.shipment.Street1.value == "") {
            themessage = themessage + ", Ship To Street 1";
        }
        if (document.shipment.City.value == "") {
            themessage = themessage + ", Ship To City / Locale";
        }
        if (document.shipment.country.value == "") {
            themessage = themessage + ", Ship To Country";
        }
        if (document.shipment.state.value == "") {
            themessage = themessage + ", Ship To State / Province";
        }
        //alert if fields are empty and cancel form submit
        if (themessage == "You must provide the following information") {
            window.print();
            return false;
        }
        else {
            alert(themessage);
            return false;
        }
    }
</script>

I would like to create a print preview window that will display only the main content of the page that a person would really want to print. I found a script that didn't do that, but that I was able to adapt, somewhat. It doesn't fully work though and I can't get it any better. Here is what I have...

<html>
<head>
<title></title>
<script LANGUAGE="JavaScript">
function displayHTML(printContent) {
var inf = printContent;
win = window.open("print.htm", 'popup', 'toolbar = no, status = no');
win.document.write(inf);
}
</script>
</head>
<body>
<div id="printarea">Print this stuff.</div>
<a href="javascript:void(0);" onclick="displayHTML(printarea.innerHTML)">Print Preview</a>
</body>
</html>

In mozilla it opens the new window but continues to be thinking about something indefinitly. In Safari the new window opens but there is no content. In IE it seems to work fine. I haven't tested NS yet, nor have I tested any of this on a PC.

Thanks for any help.

Hi everyone! I need a little help with something. I have a page with several links that when clicked open a modal window. The same window for each link, with a form. However inside the form I need to print the id of the link that was clicked. Like so:

<a href="#" id="1">Link 1</a>
<a href="#" id="2">Link 2</a>
<a href="#" id="3">Link 3</a>

<form>
....somehow print/echo the id of the link...
</form>

Is this possible? Does anyone know how to do that? I'd appreciate any help!

Hi,

anyone any ideas?

I've searched and searched. It seems the sages, and experienced programmers think var dashes = "------------"; is the easiest way. Certainly there must be some simple (or not as simple) way of printing a line of dashes in javascript without declaring a variable as "----------" (that's just sloppy)

I don't mean to be rude but this should be easy. Right? Or must I resort to a loop (probably an integer count) that ends at a declared number like 10 or 20?

Thanks, And I really think this thread will come in useful to many others (in future searches) who have had just as hard a time as finding this as I.

Thanks again.

I have the some text loaded in light box with background faded.


i want the print button in the light box so that when user click on that only the contents of light box is printed and printer box opens up.

How to do that??

Hi all. I am having a problem understanding exactly how setInterval and setTimeout work and really need some help.

I want to create an array and then print out each element one at a time at one second intervals.

I've only been able to come up with something like this, but it just prints the last value of the array after a second.
Code:

<script type = "text/javascript">
<!--

var myArray = new Array();

for (var i = 0; i < 11; i++){
   myArray[i]=i+50;
}

for (var i = 0; i < myArray.length-1; i++){

   setInterval("document.getElementById('here').innerHTML = myArray[i];", 1000);
}



//-->
</script>

<div id="here">Stuff here</div>

Hi,

I'm using window.print() to print a document.

This is the coding :

<th colspan="2" align="right"><a href="JavaScript:window.print();" onclick="return verify()"><img src="image/image.gif" width="25" height="20" /></a></th>

How can i print the document without printing together the image?

Or is there any other way that you guys know?

Thanks
