1. Install the required driver for your distro
Debian:
sudo apt install printer-driver-escpr
Fedora:
sudo dnf install epson-inkjet-printer-escpr
Arch:
yay -S epson-inkjet-printer-escpr
2. Enable and start the CUPS service
sudo systemctl enable cups && sudo systemctl start cups
3. Add the printer via CUPS web interface
Go to http://localhost:631, then navigate to Administration > Add Printer, select the printer on your network and follow the prompts. When choosing the driver model, pick the closest match — for the L355, the L405 or L455 works well.
