Nokia 6600: Bluetooth Printing (BPP) Problem

Hi,

The Printing Application in 6600 is having some problems. It has been
found that, application do not recognise other Bluetooth BPP Printing
Services, so it displays "Not a BPP enabled Bluetooth printer" !!!

My experience:
Step1> Started a Bluetooth BPP Service with all the values specified in
the BPP SPEC 1.0
Step2> Started Printing Application in 6600, ..., searched for
Printers, -- My Printer got listed
Step3> Selected My Printer in the Phone
Step4> The phone displays "Not a BPP Bluetooth Printer"..!!!

(I used a Bluetooth Sniffer to catch the Bluetooth packets over air. It
is found that, the phone requests [SDP Requests] for Direct Printng
Service [Object channel] and Supported Document Formats [Attr ID:
0x0350]. The required information is returned)

Why this phone behaves like this? Any one has got a clue ???
I tried several times, but everything failed

Am i missing something?
Or the Printing Application is having interoperability problems?

regards,
Reghunath
