Error message received from system Error while reading filter description for true
 

Ran in to a problem a bit weird with few info on it on the web.

It's seems like a bug in KDEprint

If ever you notice you can't print from any KDE apps anymore and encounter the following error message:
I have found the soltution. A filter called TRUE is being created in a unknown fashion. It needs to be deleted in the printer properties filter tab.

Tought I would share.

Thanks, i've been pulling my hair out.

My pleasure
