Had to fix up serveral Kyocera Mita KM 1650 KX and Kyocera Mita KM 2550 KX “printers” here. Quite fancy and they support every printing protocol I could imagine, so should be easy right? Unfortunately the documentation is quite scarce. And the model/type of the Kyocera’s on this network were not available in the default driver list of CUPS.
Half of the work is to fetch the PPD file. I found the PPD’s I needed at linuxprinting.org/download/PPD but you can also get it from the Kyocera website or driver CD.
Although you can spend several hours clicking and messing around with several graphical frontends I recommend using the command line tool `lpadmin`.
sudo lpadmin -p MyKyoceraPrinter -E -v socket://192.168.1.100:9100 -P Kyocera_Mita_KM-2550_en.ppd
If the ppd file is not in the current directory you have to specify the full path. Thats all. 
At first I tried to add the printer with the ipp protocol but failed (if you managed please leave a comment). Since the JetDirect way works I didn’t investigate this further.
