I've managed to install the Kyocera_FS-1025MFPGDI.ppd in the /usr/share/cups/model/Kyocera folder successfully and copied the rastertokpsl file into the /usr/lib/cups/filter folder.
With printer on and usb plugged in I've tried to add printer and everything looked ok but I couldn't even print a test page. I removed printer and tried again and again.
Everything seems ok when printer is added but no printing at all. The troubleshoot wizard says there's no specific solution for my problem.
Printing test page gives message Printing stopped 'Test page' on FS-1025MFP
