Epson ET-m3140 printer on Raspberry Pi400 install problem

Dear Manjaro users,

firstly I would like to apologize for my poor English.
As of today I am using Manjaro 21 KDE as my base system on the Raspberry pi 400.
I don’t have another pc / laptop, so I am dependent on it.
Before Manjaro I used Raspberry Pi OS.

Now I want to install my Epson ET-3140 printer.
But I can’t do it, it works differently than the Raspberry Pi OS 'deb’file.
I downloaded the official driver here:

This contains a ‘tar.gz’ file that I extract with Ark.
But which step should I follow next?
I tried to run the commandlines here, but unfortunately to no avail:

Can someone please help me?
Thank you in advance.

Why not using the PKGBUILD?

To install this driver, just type

pamac build epson-inkjet-printer-escpr2

It clones the recipe and build a package for you.

Here is what it does: PKGBUILD - aur.git - AUR Package Repositories

In the first place (after using the code) it gave a error:

After that i looked in the Manjaro software installer and found the packed.
It installed very well, but what is the next step?
