In the print dialog, the default is to create individual files. This is rarely a good idea, especially if you have set of 150+ pages.
Furthermore, there is no way to cancel the whole operation if you accidentally let it print your 150 pages individually. You have to sit there and say cancel 150+ time or forcefully close and restart Revit, assuming you had remembered to save before.
I would suggest you use "Combine Separate Views/Sheets into a single file" as the default.
Also, give us an option to cancel the whole printing operation when we make the error to print the pages individually. This is a large source of frustration in the office and it could be solved easily.
