A general-purpose workaround if your printer driver stops working is to remove and reinstall the driver.
I noticed that you can't use the provided menu option to uninstall the Samsung Unified Driver. Instead in Kubuntu you need to do the following:
sudo /opt/Samsung/mfp/uninstall/uninstall.sh
Simply then reinstall the driver as noted above. There's no need to remove the extra files mentioned in step 4 if you're reinstalling.
