PDF Printing

Print.js was primarily written to help us print PDF files directly within our apps, without leaving the interface, and no use of embeds. For unique situations where there is no need for users to open or download the PDF files, and instead, they just need to print them.

One scenario where this is useful, for example, is when users request to print reports that are generated on the server side. These reports are sent back as PDF files. There is no need to open these files before printing them. Print.js offers a quick way to print these files within our apps.

PDF files must be served from the same domain as your app is hosted under. Print.js uses iframe to load files before printing them, therefore, it is limited by the Same Origin Policy. This helps preventing Cross-site scripting (XSS) attacks.

Example

Add a button to print a PDF file located on your hosting server:


 <button type="button" onclick="printJS('docs/printjs.pdf')">
    Print PDF
 </button>

Result:

For large files, you can show a message to the user when loading files.


 <button type="button" onclick="printJS({printable:'docs/xx_large_printjs.pdf', type:'pdf', showModal:true})">
    Print PDF with Message
 </button>

Result:

The library supports base64 PDF printing:


 <button type="button" onclick="printJS({printable: base64, type: 'pdf', base64: true})">
    Print PDF with Message
 </button>

Result:

HTML Printing

Sometimes we just want to print selected parts of a HTML page, and that can be tricky. With Print.js, we can easily pass the id of the element that we want to print. The element can be of any tag, as long it has a unique id. The library will try to print it very close to how it looks on screen, and at the same time, it will create a printer friendly format for it.

Example

Add a print button to a HTML form:


 <form method="post" action="#" id="printJS-form">
    ...
 </form>

 <button type="button" onclick="printJS('printJS-form', 'html')">
    Print Form
 </button>

Result:

Print.js accepts an object with arguments. Let's print the form again, but now we will add a header to the page:


 <button type="button" onclick="printJS({ printable: 'printJS-form', type: 'html', header: 'PrintJS - Form Element Selection' })">
    Print Form with Header
 </button>

Result:

Image Printing

Print.js can be used to quickly print any image on your page, by passing the image url. This can be useful when you have multiple images on the screen, using a low resolution version of the images. When users try to print the selected image, you can pass the high resolution url to Print.js.

Example

Load images on your page with just the necessary resolution you need on screen:


 <img src="images/print-01.jpg" />

In your javascript, pass the highest resolution image url to Print.js for a better print quality:


 printJS('images/print-01-highres.jpg', 'image')

Result:

Print.js uses promises to make sure the images are loaded before trying to print. This is useful when printing high resolution images that are not yet loaded, like the example above.

You can also add a header to the image being printed:


 printJS({printable: 'images/print-01-highres.jpg', type: 'image', header: 'My cool image header'})

Result:

To print multiple images together, we can pass an array of images. We can also pass the style to be applied on each image:


 printJS({
  printable: ['images/print-01-highres.jpg', 'images/print-02-highres.jpg', 'images/print-03-highres.jpg'],
  type: 'image',
  header: 'Multiple Images',
  imageStyle: 'width:50%;margin-bottom:20px;'
 })

Result:

JSON Printing

A simple and quick way to print dynamic data or array of javascript objects.

Example

We have the following data set in our javascript code. This would probably come from an AJAX call to a server API:


 someJSONdata = [
    {
       name: 'John Doe',
       email: 'john@doe.com',
       phone: '111-111-1111'
    },
    {
       name: 'Barry Allen',
       email: 'barry@flash.com',
       phone: '222-222-2222'
    },
    {
       name: 'Cool Dude',
       email: 'cool@dude.com',
       phone: '333-333-3333'
    }
 ]

We can pass it to Print.js:


 <button type="button" onclick="printJS({printable: someJSONdata, properties: ['name', 'email', 'phone'], type: 'json'})">
    Print JSON Data
 </button>

Result:

We can style the data grid by passing some custom css:


 <button type="button" onclick="printJS({
	    printable: someJSONdata,
	    properties: ['name', 'email', 'phone'],
	    type: 'json',
	    gridHeaderStyle: 'color: red;  border: 2px solid #3971A5;',
	    gridStyle: 'border: 2px solid #3971A5;'
	})">
    Print JSON Data
 </button>

Result:

We can customize the table header text sending an object array


 <button type="button" onclick="printJS({
	    printable: someJSONdata,
	    properties: [
		{ field: 'name', displayName: 'Full Name'},
		{ field: 'email', displayName: 'E-mail'},
		{ field: 'phone', displayName: 'Phone'}
	    ],
	    type: 'json'
        })">
    Print with custom table header text
 </button>

Result:

JSON, HTML and Image print can receive a raw HTML header:


<button type="button" onclick="printJS({
		printable: someJSONdata,
		type: 'json',
		properties: ['name', 'email', 'phone'],
		header: '<h3 class="custom-h3">My custom header</h3>',
		style: '.custom-h3 { color: red; }'
	  })">
	Print header raw html
</button>

Fe Fake Lag Script Site

FE Fake Lag Script is a specialized Lua script used in exploiting to simulate high latency or poor network conditions. These scripts are designed to work within the Filtering Enabled (FE) environment, which is a security feature that prevents client-side changes from automatically replicating to the server and other players. Mechanics and Purpose Visual Deception : The primary goal is to make a player's movements appear choppy or "stuttery" to others, mimicking a low-performance device or bad internet. Positional Freezing : Some versions work by anchoring the player's character temporarily. This allows the user to move freely on their own screen while their character remains stationary for everyone else. Combat Advantage : In games like sword fighting, players use this to attack others while their own character appears to be lagging at a safe distance. : It is often used to annoy or trick other players into believing the user is experiencing technical difficulties. Implementation Methods Standalone Scripts : Individual scripts executed via third-party software that often include a for toggling the effect. Integrated Commands : Features within broader admin command hubs, such as "Shattervest," where commands like stutter on trigger the effect. Custom GUI Controls : Advanced scripts allow users to adjust specific variables to control the severity of the fake lag. Usage and Risks Vulnerability : While active, other players can often still attack the user's stationary avatar. Detection & Bans : Using these scripts is typically a bannable offense in most games. While it may not result in a platform-wide ban from Roblox, it often leads to being kicked or banned from specific game servers. Security Concerns : Downloading scripts or executors from untrusted sources can expose your device to malware. Using a test account is recommended by community members to avoid compromising a primary profile. FE Fake Lag Script - ROBLOX EXPLOITING

In Roblox, an FE Fake Lag Script is a tool used by exploiters to simulate a poor network connection while maintaining a tactical advantage in-game. "FE" stands for Filtering Enabled , a core Roblox security feature that prevents client-side changes from affecting the server unless specifically permitted. What Does It Do? The script creates the appearance of lag by manipulating how a player's character data is sent to the server. Key features often include: Stationary Avatar: The user's character appears to stay in one spot on other players' screens while the user actually moves around freely. Delayed Positioning: When deactivated, the user's character "teleports" to their current actual location, often confusing opponents. Combat Advantage: In games like sword fighting, users can attack others while their own "hitbox" remains stationary and difficult to target accurately. How It Works These scripts typically use a few common methods to achieve the "fake lag" effect: Replication Lag: They may delay or drop data packets being sent to the server. FPS Manipulation: Some versions lower the user's frame rate to extreme levels (e.g., 1 FPS) to stutter their movement for others. Looping Anchors: Scripts may rapidly "anchor" and "unanchor" the player's character to create a stuttering, laggy visual. Risks and Ethical Use While some developers use built-in Roblox Studio settings like Incoming Replication Lag to test how their games handle poor connections, using third-party scripts in live games is considered cheating. Terms of Service: Using these scripts to gain an advantage violates Roblox's Terms of Service. Bans: Roblox's anti-cheat systems can detect many of these manipulations, leading to temporary suspensions or permanent account bans. Security Risks: Downloading scripts from unverified sources can lead to account theft or malware. Are you looking to use this for game testing in Studio, or are you interested in how to prevent these exploits in your own game? FE Lag Switch Script - ROBLOX EXPLOITING
