Depends on which problem you refer to. For printing there are multiple devices. I prefer
kcm_printer_manager which is the module in SystemSettings5. There is also the age old
system-config-printer. However OM devs do not install all the printer drivers by default so the user needs to do that. That is mainly what the post in the OM Lx 4.2 Errata is about. To install "most’ available drivers I thinks is still:
$ sudo dnf install task-printing
But I think your printer is unique and needs a driver for Xerox printers (Xerox Phaser 6000B)? Don’t know yet if that is in our software.
Note: You can ask our developers to package that driver for your printer if it works.
If your are talking about the USB floppy issue the link has simple instructions that would take seconds to do. Whether there is some “device manager” to do that I do not know, maybe there is.
Edit: I deleted my first answer to this as it did not address which problem was being discussed.
Hope this was helpful.
