A user's MS CRM report size always changed.

I designed MS CRM Reports using "SQL Server BI development Studio", and define the report size. Everything's fine until, one day, a user reported the report (label) size changed to a much larger size, and the label printer printed out 3 pages, including 2 blank pages. The user had to change the report's size everytime.

Users use Windows RDP service, everyone actually works on the same server. I tested in my session, and everything's fine.

When MS CRM print out report, it should setup printer for the pre-defined size, so, this error mad nosense. I checked all related setting on the user, no clue.

Finally, I noticed that the user and me had different printer as "default printer". I change the user's default printer to mine, suddenly, problem solved.

I have no ideas how it happen, and why it had be solved, just as a reminder.

This is an interested case to show that MS Windows are full of out-of-mind bugs.
