Q
What happens when you call the window.print() method in JavaScript?

Answer & Solution

Answer: Option Option B
Solution:
When you call the window.print() method in JavaScript, it triggers the print dialog in the browser. This dialog allows users to select printing options such as the printer, page range, and number of copies before initiating the printing process. The method does not open a new tab or window, close the current window, or display an error message. Its primary function is to facilitate printing functionality within web applications by interacting with the browser's print dialog and settings.
