There are literally thousands of fonts (typefaces) available over the internet.  Whenever you send your files to your printing company, always send a copy of the fonts you have used, particularly if the font is unusual or rare.  By doing this you will speed up the time the print company spends on your job, saving them time and irritation.

On the PC, (Windows XP) this can be done by clicking Start, Control Panel, Fonts.  Then click and drag the file onto your CD or Email.
