of that receipt printer.

but when i give a print on red color string
it s printing in black color only

whether i have to change in .gpd file
to support that red color printing feature.

Do you mean NT4 when you say “nt machine”? Or is it W2K? On NT4 the
printing model is a minidriver (GPC file) that goes with rasdd.dll. On
W2K, the minidriver (GPD file) goes with unidrv.dll. Since you have a
GPD file, I am assuming that your target platform is W2K.

As for why the printer does not print color, you will have to specify
color printing in the gpd. Please refer to the DDK docs for more info on
this. Look under the section on GPD files and Handling Color formats.
