Asset scan for Printers routers and switches

Asset scan for Printers routers and switches

While doing an AD scan for assets, I noticed only workstations, servers and some printers are found.
We have around 44 printers in our AD domain (most of the same make and model) The AD scan however does not detect all of them. For some reasons some printers are being skipped on every scan while the setup is excactly the same for all of them.
Also routers and switches are not found. How can I detect these?
