You should be able to set this printer up with ease. If you installed eos with print support then cups should already be installed. You need to install hplip with sudo pacman -S hplip
Install system-config-printer,a GUI tool to configure printers.
Start system-config-printer and click the button to add a printer. Select your printer and choose HPLIP as the connection method.
system-config-printer should now allow you to print a test page.
In order for a GTK application like Evince to show your printer in the printing dialog, you need to install gtk3-print-backends as well.

Instead of system-config-printer described above, you can also use CUPS’ web interface, reachable at localhost:631
