Well written article Wagner. I have used SQL Diagrams since SQL 2000 and find them indispensible in my work. Lately they have been causing me a major problem when attempting to print.
Currently am using SQL Server Management Studio 2008 version 10.0.2531.0. I have found that when I attempt to print (to a physical printer, to PDF, etc.) the entities shift down so that they cross the blue page lines. This is very frustrating as I spend a considerable amount of time organizing the entities and the text descriptors only to have the print attempt skew the whole drawing.
I did a couple screen captures so you can see what happens.
This is the diagram before printing. I've covered up text descriptions with orange rectangles.
This is the diagram immediately after I choose, File, Page Setup. Note how all of the entities have shifted down.
If you or anyone reading this has any idea if there is a patch for this bug I would appreciate knowing about it.
