Thanks a lot for prompt replies. I also followed https://wiki.ubuntu.com/DebuggingPrintingProblems and got the debug logging (error_log) mentioned in the "CUPS error_log" section and the "printout" mentioned in the "Capturing print job data" section. I attached them now in case they are still useful.
