Question
“How can I shrink the font to force the report to produce a single page?”
Solution
This example contains a pre-processing step that generates the report pages to a dummy output device. If more than one page is produced, then the font size is adjusted. Following the pre-processing step, Report.Print is called to generate the report to preview.
