There are large similarities between Charles Babbage's Difference Engine No. 2 and the Analytical Engine. Critically, Babbage designed the Difference Engine No. 2 after the Analytical Engine and it incorporates improvements discovered during the design of the Analytical Engine.
And the printer that's part of the Difference Engine No. 2 is identical to the printer needed for the Analytical Engine. Babbage said that the same printer would be used for both. The memory of the Analytical Engine is very similar to the figure wheels in the Difference Engine No. 2.
Here's Doron Swade demonstrating and explaining the Difference Engine No. 2:
And here's a lovely video of the machine in motion. Now try to imagine the Analytical Engine which will have 8x the number of parts and be vastly bigger.
