CE testing and marking for IoT

Hello, our company is developing an IoT device for realtime label inspection on industrial desktop thermal label printers. Not entirely sure what will be applicable to this, in terms of Directives, probably not the LVD as it’s powered by only 5 volts or less. Presumably, EMCD and possibly others?

If you work in this area and offer services relating to the above (testing, verification of technical file etc) please let me know! Seeking assistance with this project so we can get it to market.
