how to use printer fonts in crystal Help plzzzz..

I have a problem with regards to fonts in crystal reports. I would like to use the printer font. I read in crystal report help file that it is recommended to use true type font to avoid incompatibilites with printers. I dont want to use true type fonts in a dot matrix printer coz its too slow to print. If i can only use the printer fonts that would be great. Since my app is using a specific printer i dont see any problem with compatibilities. We are not going to use different printers anyway. Specifically i'm using a epson lx-300+ dot matrix printer. I cant seem to find a way to change my fonts to printer font. any suggestions? :confused:
