- For other "CPI" formats, see: Blu-ray Clip info, CPI (ColorLab), Marco Pixel Editor, Cartesian Perceptual Compression.
CPI is a font (or at least font-related) file format associated with MS-DOS.
FreeDOS also supports CPX files in addition to CPI; they are CPI files compressed with UPX as if they were COM files.
See also DRFONT, for a variant used by DR-DOS.

[edit] Discussion
A CPI file typically contains fonts from a single typeface, with support for multiple code pages, each rendered at multiple font sizes.
A CPI file usually contains either screen fonts, or printer fonts. A printer font can be just the instructions used to select a font that is built into the printer, or it can be actual font data to be sent to the printer.
[edit] Identification
CPI files begin with 0xff "FONT ", or 0xff "FONT.NT".
