Print preview doesn't go past column FB. Why?
 

I am working with a flowchart that was created by someone else. My problem
is when printing to a plotter. The flowchart extends to column GU. When I
look at a print preview, the flowchart ends at column FB. I've extended the
page length to GU as to set the print to be 1 page in length. Since it will
print on a plotter with 24" wide paper roll. I cannot find any settings
that may limit me to column FB. What am I missing? Any help would be
appreciated.
