Question: Is it possible from FastReport to set a different printer ?

Answer:

Maybe you want to use a diffrent printer in the report definition (the 
*.fr3-file) so that this printer becomes the default printer for this 
specific report? To do this in the report designer choose "Options..." in 
the "Report"-menu. Select the "General" tab in the dialog and choose desired 
printer in the printer list.
Of course you can also select/alter printer from the preview window or by code from your delphi application.
