Junk Characters are coming in the Print Preview of True Type Font

Hi

I am facing one issue. Here I have installed on one of the True type font of Gujarati (one of Regional language for India) language.When I see Print preview using LP01 Output device (which has SWIN Device Type) these true type font coming as Junk characters. But when I take print it is coming perfectly Ok. I want to know is there any setting required to maintain for Output device to see Print Preview in Gujarati also ?

I feel that when System is generating output for Preview it is ignoring true type font..

If there is any solution kindly let me know

Regards
