Q
Which JavaScript method is used to open the print dialog programmatically?

Answer & Solution

Answer: Option Option C
Solution:
The window.print() method is used to open the print dialog programmatically in JavaScript. This method triggers the print dialog, allowing users to select printing options and initiate the printing process. It is commonly used in conjunction with print buttons or print-related actions to enable printing functionality within web applications. The window.alert(), window.open(), and window.confirm() methods are not used for opening the print dialog; they are used for displaying alerts, opening new windows, and confirming actions, respectively.
