Final answer:
To successfully add a shared network printer to a SOHO environment with network hardware address filtering, a technician needs to know the printer's MAC address.
Step-by-step explanation:
In a SOHO (Small Office/Home Office) environment with network hardware address filtering, a technician needs to know the printer's MAC address to successfully add a shared network printer to the environment. MAC address filtering is a security feature that allows or blocks network access based on the hardware address of a device.
By knowing the printer's MAC address, the technician can add the printer to the address filtering list, allowing it to communicate with other devices on the network. This ensures that only authorized devices can connect to the printer.
Other information such as the printer's brand and model, ink or toner level, and color printing capabilities are not essential for adding a shared network printer in an environment with network hardware address filtering.
