What is an SFP file?
Font file used by some printers; saves bitmap graphics that represent the glyphs of the font that can be printed; commonly named MICR.SFP and can be loaded on the printer using programs included with the printer purchase (examples include FLOAD.exe, HP Web Jetadmin utility, and TROY Printer Utility).
With some printers, you can also store company logos and forms in the SFP files so they can be automatically printed on company documents.
