Thanks Ashraf for your post. I looked at it and while it is helpful in its suggestion to turn on the "view page breaks" feature of SQL Enterprise Mgr / SQL Management Studio Diagrams, it doesn't address what my problem was.

On page 1 of the thread is where I placed my original question.

To summarize, the problem wasn't with viewing the page breaks. I had this turned on just fine and had aligned my tables precisely within the page break boundaries. See this BEFORE screen capture to see how the diagram looked: http://www.sqlservercentral.com/Forums/Attachment9866.aspx.

When attempting to PRINT this diagram though, all of the tables would shift so that they were no longer lined up the way I had placed them in the diagram. Here is what would happen as soon as I chose to PRINT the diagram: http://www.sqlservercentral.com/Forums/Attachment9867.aspx

You will notice, in the AFTER screen shot that all of the entities in the diagram have shifted down about 1/2 of a page so that they are now crossing the page break boundaries.

Jeff Moden responded to my question shortly after posting to tell me to that I needed to place one of my entities closer to the bottom edge -- as SQL Management Studio was (un-helpfully) trying to center my diagram before printing. By moving some of the entities so that they were NEAR the top boundary AND NEAR the bottom page break boundry -- the diagram would then print properly.
