Changing font size for Printer object

Does anyone know how to change font size in using the Printer object? I have 2 applications, one as a DOS-based Clipper application, the other was the same application but created in VB 6.0. The reports for both applications are printed in a dot-matrix printer. When I print my reports in VB using the Printer.Print command, I get smaller fonts, therefore, more lines are printed on a page when compared to the output of my DOS application. Thanks in advance.

Printer.FontSize = "10"
