Attribute Identifier List : (2110,0030) (0008,0070) (0018,1020) are not supported.
These are optional attributes that an SCP may or may not support. DICOMscope does not. If the SCU aborts the association because of the N-GET-RSP, then this is a protocol violation on the side of the SCU.
So I'm afraid that it can not be used for my App.
In that case your "App" does not correctly implement the DICOM Print Management Service Class. That said, many SCUs are not 100% correct, and the SCP component in DICOMscope has deliberately been developed to be very strict - within IHE (Integrating the Healthcare Enterprise) it is used as a test tool to check DICOM print implementations.
And DcmScope only support (2110,0010) (2110,0020) by its CS?
