Thank you. I’m not familiar with how to make a PKGBUILD but, in looking over the one provided on the AUR page to which you kindly linked, it appears that it starts with the 1lsb3.2.src.rpm which is the version released in 2012. At first, I thought that was the date last modified indicating that it may not be up-to-date.
The two drivers (rpm versions) released in 2024 are:
epson-inkjet-printer-escpr-1.8.5-1.x86_64.rpm and
epson-printer-utility-1.1.3-1.x86_64.rpm and
However, the escpr version caused the user in this AUR post to have issues (see #30) and, as can be seen in that same thread, a patch was needed to get the 2012 version to work for that user (see #31). Also, on page 1 of that post, it was noted that the PKGBUILD may have needed changes but the build system was quite old (see #24) making it not possible to make the changes that poster felt should be made. But that was in 2017 and the last update to the 201114w package was 2021-02-26; so, it may have been fixed; but, in 2021-10-17, the comment on the AUR site reads that the user still needed to make changes to get it to work.
One is left wondering if the 2012 version is the correct option or if one of the versions released in 2024 might be better suited; yet, one of those may cause issues and the AUR package is for the 2012 version only. The 2012 version may require some form of patch and that’s beyond my knowledge.
Using the AUR always feels like a risk, and if it installs without messing something else up, it still may not actually work. I may still try installing it on a machine that I can risk having down for awhile, but, overall, it just doesn’t seem worth the risk.
I’m not complaining but only attempting to explain what I meant by wasting time. Linux provides features and software that has made it possible to accomplish a lot of work efficiently, but printing is a short coming; I suppose of the printer manufacturers for not providing linux drivers. In this case it appears they have but not directly for Arch linux.
