Script Printing Problem ( urgent )

Hi Gurus

We are facing a problem when taking the print out in Dot matrix (Epson or Wipro) printer. We have set the default printer settings in Draft mode but while printing it changes to Roman font mode automatically.

How to fix the font family as Draft by default? Is there anything to be done in SAP script or print program?

Or any other settings to be done in SAP?

N.B. Points will be surely rewarded for helpful answers. Its very urgent.

Thanks in advance
