The correct answer is: Form.
A form is a graphical user interface (GUI) element that allows users to interact with a computer program. Forms are typically made up of a number of controls, such as text boxes, buttons, and check boxes, which users can use to enter data or select options.
When a user prints a document, the form that they are using to enter data must be active in order for the print command to be executed. This is because the print command needs to access the form in order to print the data that is entered into it.
The other options are incorrect because they are not necessary for printing. An application is a program that runs on a computer. A code editor window is a window that is used to edit code. A timer is a device that measures time.
