Question: he says "divide the poster up," and remove some of the borders that are artifacts of the printing mechanism. I get that. All he has to do is specify a very large banner-size paper, and it will break up automatically. Is there anything further?
You want to provide overlap in your prints, which gives you wiggle room when you trim off the edges. More overlap means more wiggle room for your cuts at the expense of more paper used. Publishing software can do this for you on the way to the printer! See relevant help articles, below:

SABO is going as CHEAP as possible... 11x17" paper B&W was cheapest, cost hom nly $1.80 to make that poster plus about 20cents tape :-)

Will that break it up with overlap? My guess would be no. I think you may need to do some manual manipulation to get the overlap.
