Printing on Archlinux or generally Linux is not easy. Thus manual is a guide on how to achieve printing on Archlinux.
Note that I highly recommend the Archlinux Wiki which is more deep and explains the concepts better. My guide shall achieve the same results but faster.
Install the required packages for printing. CUPS is the standards-based, open source printing system developed by Apple Inc. for macOS® and other UNIX®-like operating systems.
sudo pacman -S cups cups-pdf hplip libcups system-config-printer
Add yourself to the lpadmin group to access the printing service.
sudo groupadd lpadmin sudo usermod -aG lpadmin username
Edit the /etc/cups/cups-files.conf and add the SystemGroup line.
sudo nano /etc/cups/cups-files.conf SystemGroup sys root lpadmin
Start the CUPS service. CUPS provides a org.cups.cupsd.socket unit. If org.cups.cupsd.socket is enabled (and org.cups.cupsd.service is disabled), systemd will not start CUPS immediately, it will just listen to the appropriate sockets.
Then, whenever a program attempts to connect to one of these CUPS sockets, systemd will start org.cups.cupsd.service and transparently hand over control of these ports to the CUPS process.
This way, CUPS is only started once a program wants to make use of the service.
sudo systemctl enable org.cups.cupsd.service
Reboot your machine for the changes to take place.
Afer rebooting launch system-config-printer from the terminal, then enter your username and password.
