Description
Specifies the factor by which the printed output is to be scaled. The apparent page size is scaled from the physical page size by a factor of dmScale/100. For example, a letter-sized page with a dmScale value of 50 would contain as much data as a page of 17- by 22-inches because the output text and graphics would be half their original height and width.
