'lpstat -p' always reports a request ID is '-0'.

Issue

• "lpstat -p" always reports a request ID is "<printer-name>-0". On our own system, "lp -d" reports a request ID is as follows.

  # lp -d VSP4620AFM J1_20p.txt
   request id is VSP4620AFM-4 (1 file(s))
  

• "lpstat -p" run to confirm the printing request information reports as follows.

  # lpstat -p
   printer VSP4620AFM now printing VSP4620AFM-0.  enabled since Fri May 14 14:36:12 2010
  

• As you see, the request IDs are different from each other.  That is, "lpstat -p" should be report VSP4620AFM-4 as well as "lp -d".

• Step to Reproduce:

      1. Run "lp -d" to print a file.

    # lp -d <printer-name> <file-name>
    request id is PRINTER_NAME-ID (1 file(s))

     2. Run "lpstat -p" to confirm a printing status.

    # lpstat -p

• Actual Results: "lpstat -p" always reports a request ID is "<printer-name>-0".
• Expected Results: "lpstat -p" reports an actual request ID.
