I was able to install capt-src driver, available from AUR: AUR (en) - capt-src. The python2 (a dependency) package (from AUR) does not build properly (it has been deprecated). I was able to install python2 binaries available from here: Is there any way to install python2 binary? - #9 by koshikas. Now, I have both the drivers installed (as two different printers).
