>If there is such a thing as a section in Excel, it it possible that the problems I'm experiencing are related to a page size being set in such a 'section' somewhere which overides the worksheet's and workbook's page size setting?
There is: it's the worksheet. But within a worksheet there is no concept of a "section".
I have done a number of tests and I can't get Excel to do anything even close to a reasonable layout. When I set my sheet to print in A4 and draw a rectangle exactly 8.3 by 11.7 inches it doesn't fit in on the printable page. If I shrink the image to fit the size is 7.88 by 11.15. That kind of makes sense because my printer cannot print closer than about .25 inches from the paper edge. When I print that image though the size is 7.25 by 10.5. I checked all my settings and nothing is being reduced. When I lay out a page in Adobe Acrobat the dimensions are close to perfect. I have to conclude that Excel is just plain bad at doing page layout with any reasonable accuracy.
