Well, I have found refences to JCL... in docs and added <04>
in the last of the following lines (in the imported file):

*JCLBegin: "<1B>%-12345X at PJL JOB<0A>@PJL SET LMULTIPAGEPRINT=OFF<0A>"
*JCLToPSInterpreter: "@PJL ENTER LANGUAGE = Postscript <0A>"
*JCLEnd: "<04><1B>%-12345X at PJL EOJ <0A><1B>%-12345X"

Then I re-imported the file (is it OK to re-import, did it really overwrite the previous entries?) but that did not change anything.

I can see no *JCL line in the /etc/cups/ppd/lex.ppd file autogenerated by the system. Instead, I found the following there:

*cupsFilter:    "application/vnd.cups-postscript 0 foomatic-rip"
...
*FoomaticRIPCommandLine: "cat %A%Z"

which (AFAIU it right) means that a PS job is simply cat-ed to the printer, with no PJL commands added. This agrees with what I can see when I set the printer device to a file.

I have (temporarily and improperly) solved the problem by adding by hand 'echo -en "\004&quot' to the FoomaticRIPCommandLine. 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.
