Link OS Application for blue tooth printing not working on CE 7 Device MC3200


We have an application which works fine on previous version of CE.

But it is not working for Embedded 7 devices the PSDK is instaled and application is targeted to this PSDK


It is observed that the Open() method of ZebraPrinterConnection object takes indefinite time if the printer with the concerned MAC Id is on. if the printer is off it perfectly throws the exception


Can get any help on this?
