It will not only help Foomatic, other driver packages contain also 
filters which turn PostScript directly to a non-PostScript PDL. SpliX 
has a "pstoqpdl" filter and Ghostscript comes with a "pstopxl" filter. 
The PPDs of all these filters will need the '*cupsCommands: ""' line.

Thanks in advance for adding this extension.
