The printer also has an integrated scanner (after installing Simple Scan it doesn't work without them) so drivers are needed for scanner too.

All packages (source, rpm, deb, 32-bit and 64-bit for both printer and integrated scanner) are provided by the manufacturer on the official site: HERE.

I have uploaded/attached the source packages.

Printer:

{F15055}

Scanner:

{F15056}

And also on dropbox: HERE.

They are also present in AUR as cnijfilter-common-mg2400 - HERE - and cnijfilter-mg2400series - HERE.

Could I have them available for Solus?

Maybe it is useful to know that when trying to install in Manjaro, these dependencies were needed:

gutenprint
foomatic-db-gutenprint
foomatic-db-gutenprint-ppds
foomatic-db
foomatic-db-engine`
