Stop the print dialog box from appearing when using the Ctrl + P shortcut

I'm working on an Angular app and I want to prevent the print dialog from opening when pressing "Ctrl + P". To address this issue, I have implemented the following code:

 window.onbeforeprint = (event) => {
      event.stopPropagation();
      console.log('Before print');
    };

Although I can see my log in the console, the window still appears. My goal is to use html2canvas and jsPDF to capture a screen of my app instead of triggering the default print function.

Is there a way to achieve this desired outcome?

Answer №1

Try utilizing the following code snippet:

@HostListener('window:keydown.control.p', ['$event'])
preventPrint(event: KeyboardEvent) {
  event.preventDefault();
}

The prevention of printing will be active only when the specific component is visible on the screen. If you wish to prevent printing throughout your entire application, consider adding this code to your root app component.
