DRFONT is the signature of a screen font file format associated with DR-DOS. It is an incompatible variant of CPI. It seems to be very rare, except for one EGA.CPI file included with DR-DOS.

[edit] Discussion
The main difference between DRFONT and the usual CPI format is that DRFONT can store the glyph bitmaps more efficiently. A single glyph can be shared by multiple code pages, and by multiple characters within a code page. Whether this makes it a compressed format is a matter of opinion.
[edit] Identification
Files begin with byte 0x7f, then ASCII "DRFONT ".
