 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 downloaded to the printer.
