Disable Printing - DRM Feature
Learn how Web Code Protector prevents unauthorized printing and screenshots of your protected content
Introduction
Digital Rights Management (DRM) is crucial for protecting web content from unauthorized distribution. One of the key features of Web Code Protector is its ability to disable printing, preventing users from creating hard or soft copies of protected content.
Why Disable Printing?
Print prevention is essential for:
- Protecting premium content from unauthorized sharing
- Maintaining control over confidential documents
- Preventing plagiarism of copyrighted materials
- Complying with licensing agreements
How the Disable Printing Feature Works
The Disable Printing feature in Web Code Protector uses multiple techniques to prevent content extraction:
1. CSS Print Media Blocking
Injects CSS that hides all content when printing is attempted:
<style>
@media print {
body { display: none !important; }
}
</style>
This ensures printed pages come out blank.
2. JavaScript Print Prevention
Blocks browser print functionality through:
// Override print function
window.print = function() {
alert("Printing is disabled for this content.");
return false;
};
// Block Ctrl+P/Cmd+P
document.addEventListener('keydown', function(e) {
if ((e.ctrlKey || e.metaKey) && e.key === 'p') {
e.preventDefault();
alert("Printing is disabled for this content.");
}
});
3. Print Screen Protection
Detects Print Screen attempts and responds with:
document.addEventListener('keyup', function(e) {
if (e.key === 'PrintScreen' || e.keyCode === 44) {
e.preventDefault();
showModal("⚠️ Unauthorized screenshot attempts are blocked.");
clearClipboard(); // Clear clipboard data
}
});
Includes a modal warning and clipboard clearing.

Does print protection work on mobile devices?
Yes, the CSS print blocking works across all devices. However, mobile browsers may handle print screen detection differently than desktop browsers.
Can users bypass the print protection?
While determined users with technical knowledge may find ways around client-side protections, this feature effectively prevents casual printing and creates significant barriers against content theft.
Does this affect accessibility?
The print blocking only affects actual printing attempts - screen readers and other accessibility tools continue to work normally. For accessibility compliance, consider providing alternative accessible formats.
