What implementation prevents printing to networked or USB-connected printers?

Print blocking is a security implementation specifically designed to prevent printing to both networked and USB-connected printers. This measure is often used in organizations to protect sensitive information from being inadvertently printed and left unsecured. By disabling printing capabilities on certain devices or networks, organizations can minimize the risk of data leakage.

In environments where sensitive data is handled, restricting print capabilities can help ensure that confidential information does not get exposed through hard copies, which can be easily accessed or misplaced. Print blocking can be implemented through various software solutions that manage print jobs and enforce printing policies based on user roles or classification of the material.

The other options, while they have their own security functions, do not directly relate to preventing printing capabilities. Clipboard restrictions are focused on controlling data copied to the clipboard, network isolation pertains to separating networks for security purposes, and access control lists are used to manage permissions and access rights to resources, but none specifically block printing outputs.
