For many many years, it annoyed me to the most, that my laser printer DELL C1765nfw which I bought in 2014 would not work in Linux at all, I never found a driver it works, and even if you find one and install the cups package, it will not work in many cases, if you don’t do the setup process exactly as I describe it here.
I found out that there is a working printer driver available now via OpenPrinting
first open the printer settings program
Install it with the command line:
sudo dnf install cups-drivers-foo2hbpl

Then add the new printer using “Network printer” —> “Find network” printer and enter its IP, for me it is 192.168.1.60:

it finds the printer at port 9100 using for a connection the AppSocket/HPJetDirect.
Then select “Select printer from database” and use the Dell C1765

Then it is found and the Describe printer dialog fields are pre-defined correctly.

When it asks whether you want to print a test page, decline as first we need to setup the driver to allow printing in color, as per default it is setup to print in b/w only.
Change color mode from “Monochrome” to Color:

Once changes are applied, you can happily print a test page.
As for the USB floppy disk drivers, it makes me mad that it constantly probes for whether a disk has been inserted, so it constantly lids up and clicks.
While searching for a way how to read SMART data from disks, I came across this article: How to Test SSD/HDD Health in Linux 1
Its suggested GUI tool “Gnome Disks” has a button on top called “Power Off”.

Silence!
Thanks to the OpenMandriva community who gave me a helping hand and for the printer issue pointing me in the right direction after I plead for help.
