Often you will need to send with your document the fonts you have used in it. This is so we can put the fonts on our system, or download them.
Manufacturers provide limited number of fonts, called resident fonts, with their printers.
Any font that is not resident on a given printer is called a downloadable font and must be temporarily installed to print a document in which that font has been used. Screen fonts show true representation of the type on a computer screen. Printer fonts are used by the imagesetter to correctly print the type. You must provide copies of the screen and printer fonts for them to print correctly. Supply all the font variations you have used in your document.
