FM SET_PRINT_PARAMETERS (font size)

Hi Folks,

iam need to print the report output as landscape so iam calling the FM SET_PRINT_PARAMETERS. it is displaying the result in required form but the fontsize is too low. how can i increse the font size by using PRINT_CONTROL or is there any parameter in th FM itself? or is it controld by BASIS people?

ur favor is highly appreciated

Regards
