Despite the advantages of vector fonts, bit-mapped fonts are still widely used. One reason for this is that small vector fonts do not look very good on low-resolution devices, such as display monitors (which are low-resolution when compared with laser printers). Many computer systems, therefore, use bit-mapped fonts for screen displays. These are sometimes called screen fonts. A screen font basically resembles the font for a document, so that what you see on the screen will look very similar to the end-result (printed document).
