Methods and apparatus for assessing printing devices are provided. A computing device can execute a first discovery technique to send discovery messages to connected devices that can include printing devices. The computing device can execute a second discovery technique different from the first discovery technique. The computing device can receive at least a first discovery response to the discovery messages. The computing device can execute the first discovery technique to identify a first device based on the first discovery response and determine whether the first device is a printing device. After determining the first device is a printing device, the computing device can execute the first discovery technique to determine whether the first device is a known printing device based on printing device information for the first device. After determining the first device is a known printing device, the computing device can provide an output assessing the first device.
