Although it is optional for hardcopy drivers to support this function, those that do support it need to know the code page of any of the built-in fonts. For example, if only Code Page 437 is built-in, it is the code page used if 437 is requested by GreEscape DEVESC_SETMODE. If Code Page 865 is requested, a suitable code page or font could be downloaded.

This escape code is metafiled and recorded.
