Running Kubuntu 17.10.
I installed printer-driver-cups-pdf.
When I print from any application (native ones like Kate or others like Firefox), there is a default 'Print to file' printer and a 'PDF' printer like this:
I can select 'Print to file' printer and choose the filename and folder where to save the file.
But when I choose 'PDF' printer, it asks for nothing. It just shows a window as if it is sending pages to a printer. Then the window disappears. I am not able to get a screenshot of this window as it disappears pretty fast.
But where are the files? They are not in ~, ~/Downloads, /tmp or ~/Documents
