ESC/P-R package

[Diego Nicola Barbato]

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?

Greetings

Diego
