Epsondoes list printer drivers and utilities on the Epson Download Center but the packages listed are .deb and .rpm packages. I have tried building the source files but it seems that it requires lsb (and I am not sure what this means, from what I read it seems they use a different directory structure).
Thank you so much for your reply. It helped greatly. Although
pamac build epson-inkjet-printer-escpr2
did not work for me, looking through the AUR I found another that did:
pamac build epson-inkjet-printer-escpr.
