The poster utility and the kprinter tab do also work if you start kprinter as a standalone application (i.e. not from the 'Print...' menu entry of an application) and load a PostScript file into it.

- use the 'Add file' button (top on the right of the pane), or...
- start kprinter with a path to the file as a commandline parameter
(The example above loaded a JPEG image file, though.)
