The icon of a bitmapped font (also called a fixed-size font or screen font) has the single letter A on it. The font’s point size appears at the end of its name.

When you request a bitmapped character, your computer looks for an installed bitmapped font in the size you specified. (See “How the Computer Looks for Fonts” later in this appendix.) If it can’t find that font, your computer tries to construct one by scaling a size that it does find.

In most cases, scaled bitmapped fonts don’t look nearly as good as preinstalled ones. Such scaling is one reason for the jagged edges (sometimes called “jaggies”) you’ll see on your screen or in a printed document when you request an uninstalled size (for example, 17-point Geneva).

Bitmapped fonts are designed on grids of 72 dots per inch (dpi)—the standard Mac OS–based computer screen resolution. Because of their correspondence to the standard screen resolution, bitmapped fonts in preinstalled sizes always look great on your display.

When you print a bitmapped font, it prints at a resolution of 72 dpi. Because most modern printers can print at resolutions far better than this (your Color StyleWriter 6500 prints at 300 dpi or better), printed bitmapped fonts almost always have jagged edges or stairstep sides.

Fortunately, the computer can use bitmapped fonts in combination with other font formats, reserving bitmaps for the screen and other kinds of fonts for the printer.

PostScript fonts

PostScript is a page-description language that defines the characters, symbols, and images that appear on each page of a document. A PostScript font comes as a pair of fonts: an outline font for the printer and a corresponding bitmapped font for displaying type on your screen.

No bitmapped font, no menu entry: If your system doesn’t have the bitmapped font, the PostScript font name won’t appear in your font menu.
