Network Printer - Ethernet vs Wi-Fi

My view on Network Printer regarding Wired (LAN) or Wi-Fi (Wireless LAN).

To me in my experience I mentioned that I prefer LAN as I have no issues in the long run.
Example: Most people I deal with always prefer Wi-Fi printer but every time I set up perfectly and in few days later I get calls that the printer does not connect because of the signal even there connected.

I made a video on wiring a Cat6 RJ45 cabling to a Cat6 Jack on the Wall Port.
This is showing myself doing cabling as I am still learning and improving on how install Wall Port.
