I do own a Dell Color-Laser-1320c since aeons and it always worked well. I am on Debian but after a new install of Stretch (upgrade failed) it did not work any any longer. I found out how I can get it working again.
So I said it stopped working and what I mean by that is as a lpd network printer. I plugged it in via the usb interface and it was detected by stretch as Dell Color-Laser-1320c. But stretch was complaining about missing "printer driver". So I selected FX DocuPrint C525 A-AP which did work before and voila it worked like magic again (The FX DocuPrint C525 A-AP can be downloaded as rpm from FX driver side - alien - and you get a deb - it is i386 only - multiarch to the rescue just in case - for your convenience the deb is at link).
So lpd (aka networking) now. I just added a new printer with the URI lpd://IPorHostname:515/PASSTHRU, the same drivers and settings as with the usb.
So simple and stupid. The only thing I really struggle is I do not know why it works. But it still may help and save one more old printer ending up in the bin.
