1. At least one non-transitory computer-readable medium comprising computer-executable instructions that upon execution by at least one processor configure the at least one processor to perform operations comprising: receiving, from a reader device, device information based at least in part on data from at least one machine-readable representation associated with a device; determining a device identifier associated with the device using the device information; determining a diagnostic processing identifier based at least in part on the device identifier, wherein the diagnostic processing identifier is associated with diagnostic processing to be performed on the device, the diagnostic processing comprising one or more diagnostic tests to be performed on the device; determining a diagnostic processing route associated with the diagnostic processing, wherein the diagnostic processing route comprises a sequential ordering of a plurality of diagnostic stations, and wherein the device is routed during the diagnostic processing to the plurality of diagnostic stations in accordance with the sequential ordering, the plurality of diagnostic stations comprising, at least, a first station and a second station, wherein a first diagnostic test is performed at the first station and a second diagnostic test is performed at the second station; sending, over a network, instructions for routing the device according to the sequential ordering; receiving information indicative of a defect associated with the device, wherein the defect is identified at a particular diagnostic station of the plurality of diagnostic stations, the particular diagnostic station being one of the first station or the second station; associating a defect classification with the defect; determining, based at least in part on the defect classification, that the diagnostic processing is to be halted prior to the device reaching a last diagnostic station specified by the sequential ordering; determining that repair of the device is feasible based at least in part on the information indicative of the defect; generating an instruction to create a label based on the information indicative of the defect; and sending, over the network, the instruction to cause a label printing device to generate the label.
