The fonts can be classified into some categories by their characteristics.
Residence
Internal fonts or downloadable soft fonts. The internal fonts are built in the printer. They are fixed and cannot be erased or cleared.
The soft fonts are from the host. Users can download the soft fonts from the host by their needs and erased them by proper
commands to avoid memory full.
