install-dell-c1765-fedora-31.md

Driver comes from http://foo2hbpl.rkkda.com/ :

wget -O foo2zjs.tar.gz http://foo2zjs.rkkda.com/foo2zjs.tar.gz
tar xf foo2zjs.tar.gz
cd foo2zjs && make
sudo make install

Settings->Printers->(Unlock)->Add

Select the printer (Assuming network connection is OK)

Printer->Settings->Details->Select From Database

Select the Dell C1765 - and start printing :)

This was a great help to me as the foo2hbpl package I previously used seems to have been dropped from Fedora 33.

Buglet: there should be a tar command after the wget above, for example:

tar xzvf foo2zjs.tar.gz

In later Fedora versions you can simply do sudo dnf install foo2hbpl and that'll get you C1765 support that works. I've just tested this in Fedora 38 at least.
