OK, so these will be application/vnd.cups-command file jobs.  You can comment out the cupsCommands and cupsFilter (for that type) lines from the PPD files to eliminate these jobs, but they should *never* produce any output.  If they do, that's a bug (either in the driver, or for a PostScript printer in the CUPS commandtops filter...)
