First of all, are you trying to print it within the context of Korean sentences? OR is it more of a Logo Image that you want to print?
Second of all, you're using NWP, right? Which version of BR?
If its within the context of sentences, then make sure you have a Korean font installed, and then use the NWP "SetFont" command to change to the Korean Font before you print that character.
If its a logo you're trying to print, then save the logo in any sort of image file, (gif, jpg, bmp, png are supported at least, probably also tiff and others). Then use the NWP "Print Image" command to print the image wherever you want.
Please verify which direction you're going with this, and i'll give you more details about the specific commands. But NWP commands are all escape codes, very similar (and in many cases, the same) as HP commands. There are a few additional commands not supported by HP such as a simpler way to change fonts and a simpler way to print images.
These NWP commands are made even easier if you want to use printer.sys to add good substitution statements.
So, assuming you're using printer.sys, the command would be the following:
PRINT #255: "[PUSH][POSITION(2,5)][PICTURE(2,2,'koreanW.jpg')][POP]"
Or else if you want to use the korean W within a korean sentence then it might be something like this
PRINT #255: "[SETFONT(MyKoreanFont)]igeos-eun hangug-ui munjang-ida.[SETFONT(Times New Roman)]"
