dcm.summary print 2 times

[dicom]

Can you please explain a little bit more what you expect and what you see?

I believe dcm.summary prints only one time.

However there may be some surprising aspects of this method, in that the method prints the information itself, and if you e.g. do puts dcm.summary, it will be two times. Is that what you mean?
