A user wants to print files from an overseas office using a shared network folder.

Comprehensive and Detailed In-Depth Explanation:

SMB (Server Message Block) is a protocol used to access files and printers over a network, including across shared network folders. It enables the user to access and print files stored remotely on a shared directory.

Option A (ADF): Automatic Document Feeder — hardware, not a network protocol.

Option B (USB): Used for direct physical connections, not for printing over networks.

Option C (PCL): Printer Command Language — relates to printer drivers, not file sharing or access.
