If your application is running in JADE thin client mode, printing is performed on the presentation client using a printer attached to the presentation client workstation.
When the presentation client requests a print preview, the pages of the printed report do not have to be transferred to and from the application server. (This optimizes the performance of the print preview process when running in JADE thin client mode over a slow network.)
However, if your application calls the Printer class setReport method to indicate that user logic subsequently stores or manipulates the report output, each page of output is transferred to the application server.
