I'm pretty familiar with Excel but I haven't done the sort of thing you're attempting with OLE so this answer is on a purely conceptual level.

Once you have created the first workbook, popped up the printer dialog and collected the user's print preferences, they are then set for that workbook, correct? You then print, destroy the workbook and create a new one without the print settings you want.

Why not clear out your data from the workbook rather than destroying it? You could then load up new data, set new title, etc. and print the "same" workbook again using the same print settings.
