For the Windows printer driver to correctly locate downloadable or cartridge fonts, the driver or a vendor-supplied utility must perform the following operations:
Install the PFM, screen font, and downloadable font files by copying them from the font manufacturer's floppy disks to the user's hard drive.
Add the softfont or cartridge settings in the WIN.INI file.
Ideally, the softfont and cartridge settings in the WIN.INI file should be set automatically by an installation program. Some Windows drivers, such as the HP LaserJet printer driver that uses PCL, contain their own font installation program. If the driver does not contain an installation program, the font vendor should make every effort to provide an installation program rather than direct the user to install the files manually.
