This article contains an overview of fonts. Additionally, it describes how to troubleshoot font problems in Microsoft Office Word 2007 and later.
A font is a graphic design that is applied to a collection of numbers, symbols, and characters. A font specifies qualities such as typeface, size, spacing, and pitch. Fonts are used to print text on various output devices and to display text on the screen. Fonts have font styles such as italic, bold, and bold italic.
TrueType fonts and OpenType fonts are outline fonts that are rendered from line commands and from curve commands. OpenType is an extension of TrueType. Both TrueType fonts and OpenType fonts can be scaled and rotated. TrueType fonts and OpenType fonts look good in all sizes and on all output devices that are supported by Microsoft Windows.
ClearType fonts are screen fonts that are optimized for an LCD screen. On an LCD screen, ClearType fonts use sub-pixel information to smooth out the fonts' jagged edges.
In most programs that support printing, you can select among different printer fonts. Printers that offer the widest assortment of fonts include laser printers, ink-jet printers, and dot-matrix printers. You can divide printer fonts into the following three categories:
Internal fonts
Internal fonts are also named resident fonts. Laser printers, ink-jet printers, and dot-matrix printers frequently use internal fonts. Internal fonts are already loaded into the printer's read-only memory (ROM). Internal fonts are always available for printing.
Cartridge fonts
Cartridge fonts are stored in a cartridge or in a card that plugs into the printer. To expand a printer's set of internal fonts, you can install font cartridges. Or, you can load fonts from software.
Downloadable fonts
Downloadable fonts are also named soft fonts. The computer sends downloadable fonts to the printer's memory when the fonts are required for printing. Laser printers and other page printers frequently use downloadable fonts. Some dot-matrix printers also use them. To increase printer speed, you should install downloadable fonts locally on client computers that print to Windows print servers.
For each document that you print, Windows may have to send the screen fonts and the downloadable fonts that the document requires to the printer. To increase printer speed, use the following techniques:
Not all printers can use all three types of fonts. For example, pen plotters cannot ordinarily use downloadable fonts. For more information about the types of fonts that you can use, see the printer's documentation.
Raster fonts are also named bitmapped fonts. They are stored as bitmaps. A bitmap is a pattern of dots. Raster fonts are designed with a specific size and with a specific resolution for a specific printer. You cannot scale or rotate raster fonts. If a printer does not support raster fonts, it will not print them. The following fonts are the five raster fonts:
Vector fonts are useful for output devices that cannot reproduce bitmaps. For example, pen plotters use vector fonts. Vector font characters are drawn with lines instead of with patterns of dots. You can scale characters to any size or to any aspect ratio. The following fonts are the three vector fonts:

To print a sample of all the available fonts in Word 2007 and Word 2010
You can use a Microsoft Visual Basic for Applications macro to generate a list of the fonts that are available to Word. Additionally, the macro displays a sample of each font. After you have run the macro, you can print a Word document that contains the list and the samples. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

Note
Panose font mapping information is stored with the font to describe the font's characteristics. For example, these characteristics may include serif or sans serif, normal, bold, or italic. If no Panose information is available, the font appears at the bottom of the list, and it does not appear in the List fonts by similarity to box.
Before you start to troubleshoot font problems in Word 2007 and Word 2010, review the following general topics:
Always make sure that you have installed the latest service pack for your version of Windows. Several font problems have been corrected in Windows service packs.
The exact number of TrueType fonts that you can install depends on the length of the TrueType font names and of the TrueType file names.
To troubleshoot font problems in Word 2007 and Word 2010, follow these basic steps:
Make sure that you are using the correct printer driver.
Your problem may be that the default printer driver in Windows is a generic/text only printer driver, an installed fax driver, or a similar driver. To change the printer driver that Microsoft Word uses, use one of the following methods.
Important Do not select a generic/text only printer driver or an installed fax driver as your default printer in Windows.
Check to see whether the problem occurs in a new document.
Create a new Word document that is based on the Normal.dotm template. To create a new document that is based on the global template, click the Microsoft Office Button, and then click New. Click Blank document, and then click Create.
Based on what occurs in the new document, follow these steps:
If the problem with a specific font persists in the new document, try to use the font in a new WordPad document. To create a WordPad document, click Start, point to All Programs, point to Accessories, and then click WordPad.
If the problem that you experienced in Word persists in the WordPad document, the font is probably damaged. You may have to delete and then reinstall the problem font in Windows.
To delete a font, follow these steps:
Click Start, click Run, type control fonts, and then click OK.
Click the font that you want to remove.
Note To select more than one font, press and hold down CTRL, and then click each font that you want to remove.
On the Filemenu, click Delete.
Click Yesto the following message: Are you sure you want to delete these fonts?
To reinstall the font, follow these steps:
Click Start, click Run, type control fonts, and then click OK.
On the Filemenu, click Install New Font.
In the Drives box, click the drive that contains the font that you want to install.
In the Folderslist, double-click the folder that contains the font that you want to install.
In the List of fonts list, click the font that you want to install, and then click OK.
Note To install all the fonts that are listed, click Select All, and then click OK.
To turn Dark Mode back on, clear the Turn off Dark Mode checkbox. OneNote will return to matching your Mac’s current appearance setting—Light, Dark, or Auto. If your Mac’s appearance is configured for Auto, OneNote will appear light during the day, and dark during the night. (The Auto setting requires macOS Catalina (Version 10.15) or later.).
For more information about how to delete a font or how to install a font in Windows, contact either Microsoft Windows Technical Support or the vendor that supplies the font.
For more information about how to obtain help with Windows XP, click Start, click Help and Support Center, and then click Get support, or find information in Windows XP newsgroups.
Check to see whether the problem occurs when you print the document at a lower resolution.
You may have to print the document at a printer resolution that differs from the resolution at which the printer ordinarily prints. By default, most printers print at either 300 dpi (dots per inch) or at 600 dpi. To determine whether the printer resolution is the problem, follow these steps:
Click Start, and then click Printers and Faxes.
Right-click the installed printer driver, and then click Properties.
Note The steps to change printer resolution differ depending on the printer driver. For more information, see the printer's documentation.
Click the Graphics tab. In the Resolution list, click a lower resolution setting. For example, in the Resolution list, click 150 dots per inch.
Click OK.
Check to see whether the problem occurs when you print to a different printer.
The installed printer driver may not be able to correctly print the font that you want. To determine whether this is the problem, specify a different printer as the default printer. Then, try to print the document.
If the different printer correctly prints the Word document, the original installed printer driver may be damaged. Or, the original installed printer driver cannot print the document correctly. To correct these problems, use one of the following methods:
