Hello, I would like to create a package for the ESC/P-R printer driver. The recipe works on my machine (GuixSD on x86_64). Yet I am not sure about the source URL as it appears to break as soon as a new version is made available because the old link is not preserved. Should we get the source from http://http.debian.net/debian/pool/main/e/epson-inkjet-printer-escpr/ instead, even though it is an older version?
