Now my T430 Lexmark printer gets "Ready" immediately after printing the job. This file, however, gets overwritten every time I change anything in the printer configuration (even when this very printer does not change), so this is surely not the way it should be done.

It should also work when you simply add the *JCL... lines. If the 
printer does not support PJL, simply try to add

------------------------------------------------------------------------------
*JCLBegin: ""
*JCLToPSInterpreter: ""
*JCLEnd: "<04>"
------------------------------------------------------------------------------

This should work independent whether the PPD file is a Foomatic PPD file 
or not.

Where does your PPD file come from? Usually Foomatic is used to make the 
PostScript input be passed through some filter which is not a CUPS 
filter (and therefore it cannot be called directly by CUPS). Your PPD 
file makes foomatic-rip passing the data through a neutral filter:

------------------------------------------------------------------------------
*FoomaticRIPCommandLine: "cat %A%Z"
------------------------------------------------------------------------------

So it is most probably not from linuxprinting.org and also not generated 
by a Foomatic database from linuxprinting.org. Is it from Lexmark?
