After examining the fonts folder that you selected, FontDoctor has determined that some fonts do not have their "sister" PostScript font files available (sometimes called "orphaned bitmaps").
Details
On the Macintosh there are several different types of fonts used in the System. One type of font type that is used in the printing and desktop publishing industry on the Macintosh is called a PostScript Type 1 font. These fonts actually consist of two separate font files; one is called the "bitmap font" (or sometimes called a "screen font"), and the other is called the "PostScript font" (sometimes called a "printer font") For these fonts to print correctly, the Macintosh needs to have both files available. The Bitmap font is used to draw the font on the screen when you type on the keyboard, and the PostScript file is during the printing process. PostScript fonts are designed to be used for extremely high quality printing using a PostScript output device, like a PostScript desktop printer or a commercial imagesetter. During the printing process, if the PostScript font file is not available, the Macintosh has no other option but to print the bitmap font instead of the PostScript font. Since the bitmap font was designed specifically for low-resolution (72 dpi) screen drawing and not for printing, the font will appear "jagged" and "blocked" when it is printed. Because FontDoctor cannot fully interpret how the font was designed by the font designer to be printed, FontDoctor cannot generate a new PostScript font file for these fonts.
Solution
FontDoctor will move these fonts into the "Moved Fonts" folder. You should re-install the font files from your original font installer disks.
