The PPD seems to be OK (short of that you attached 2 PPDs as one file).
But what strikes me when comparing your PPD with the PostScript-PPD 
supplied by Samsung is: the latter contains JCL statements, especially the following:

*JCLBegin: "<1B>%-12345X at PJL JOB<0A>"
*JCLToPSInterpreter: "@PJL ENTER LANGUAGE = POSTSCRIPT<0A>"
*JCLEnd: "<1B>%-12345X"

I'd suggest to insert these lines into your PPD just after the line reading:
*TTRasterizer: Type42

This will switch the printer to the PostScript interpreter at the beginning
of each job.
