Adding Printer Support for Epson L3150 on Arch Linux

My printer is on network at address 192.168.138.250 .

First add CUPS:

sudo pacman -Sy cups cups-browsed bluez-cups cups-pdf
sudo systemctl enable cups    
sudo systemctl start cups

Then some other dependencies (and drivers, if you want to use some other type than Epson L3150):

sudo pacman -Sy system-config-printer
sudo pacman -Sy nss-mdns
sudo pacman -Sy foomatic-db foomatic-db-ppds  
sudo pacman -S foomatic-db-nonfree foomatic-db-nonfree-ppds

And we should install the driver for L3150, which can be achieved with an AUR package (Epson only offer .deb and .rpm packages officially):

yay -S epson-inkjet-printer-escpr

All good to go! Try to search for printer with the address, and make the system discover the driver automatically. If it says the model is exactly Epson L3150, then the correct driver should be added.
