I failed to account for a Final DG Summary before I taxied towards the runway.  My FO made me aware of my mistake and we called requesting a final DG from Operations.  We also discovered the ACARS prompt to request a final DG and we selected it.  A Final DG printout was onboard prior to takeoff.  We also discovered a printout we received at the gate that did not say final DG; but had the location of DG.  This printout may have been the Final DG summary; but were not certain as I don't recall it having a handler's file number.
Push back and taxi without verification of Final DG [Summary]. Power failure at jet bridge prior to APU power caused backlog / jam of ACARS messages. Received planned DG Summary and a change to DG showing dry ice removed; but did not request Final DG Summary until on taxi. Received Final DG Summary and no further issues ensued.
Air Carrier flight crew reported pushback from the gate without the required Final DG Summary. Final DG Summary was requested and received shortly thereafter.
