Thanks for your answer, Abdul. *MasterUnits PAIR(40800, 117600) original values for LETTER *PrintableArea PAIR(346800, 1293600) *PrintableOrigin PAIR(0,0) I want to set margin to 0.25", so according to msdn 0.25" in MU is 0.25*40800==10200 for X and 0.25*117600==29400 for Y. I've set PrintableArea to 346800-2*10200==306400 for X and 1293600-2*29400==1234800 then set PrintableOrigin to PAIR(10200, 29400). Reinstall virtual printer driver with new gpd file and have a correct result! Thank you! Regards, Renat. --- Questions?
