KPDF print error

Been printing from KPDF for quite some time,recently I got the following error. I am running Debian Stretch + TDE R 14.0.3, which is testing ..for Debian anyway. This is the error dialog with NO filters, selecting 'keep' actually prints. "The file format application/postscript\012- \012- application/octet-stream is not directly supported by the current print system. You now have 3 options: TDE can attempt to convert this file automatically to a supported format. (Select Convert) You can try to send the file to the printer without any conversion. (Select Keep) You can cancel the printjob. (Select Cancel) Do you want TDE to attempt and convert this file to application/postscript?" This is the error dialog with various filters selected, tried different combo's..same result. "The MIME type application/postscript\012- \012- application/octet-stream is not supported as input of the filter chain (this may happen with non-CUPS spoolers when performing page selection on a non-PostScript file). Do you want TDE to convert the file to a supported format?" I
