The printer font, given as a printer-resident font, a downloadable font, or a cartridge.To ensure Windows applications can generate the best possible output, the Windows environment must ultimately receive the following items for each font:
The printer font, given as a printer-resident font, a downloadable font, or a cartridge.
A screen-font file in Windows .FON file format. The font must provide a reasonable approximation of the printer font while matching the aspect ratio of the display device.
A Printer Font Metrics (PFM) file or a Printer Cartridge Metrics (PCM) file suitable for the given Windows printer driver. The files must contain the metrics for the printer font, including font face, character widths, and pair- and track-kerning information.
The font vendor must make provisions to update the Windows initialization file, WIN.INI, to make the display and printer drivers recognize these fonts. Ideally, the printer driver will contain an installation program that will read the font vendor's floppy disks, and install these files. In the absence of such a utility, the font vendor should provide a user-friendly installation program. Although Control Panel can install screen fonts, installation of printer fonts and metrics files is too specific for each device to allow for a generic installation program in Windows.
