Impossible to install Brother printer on Mac

I got a new Brother DCPL 2530 DW printer. Tried to get it installed on my Mac 10.13.6 by downloading from Brother site, several times, every time refused. always get message that this software, not being downloaded from Apple Store, it is not possible to install it on my Mac or any other device I might have. But in Apple Store and do not find any App for downloading the software of the Brother DCPL 2530 DW printer.

So I am in a fix and do not understand, at all, why I should be unable to download from Brother something I have bought from them.

Anyway, if someone has a solution I would be grateful to receive it.
