In computing, form feed is one of control characters in ASCII.  It forces the printer to eject the current page and to continue printing at the top of another. 

On CRT terminals this character is not used (usually it is made equivalent to line feed).  Theoretically it could be used to clear screen, but this is rarely implemented. Example of implimentation include the shell prompt of Bash and Tcsh.

In ASCII, form feed is defined as 12 in decimal and 0C in hexadecimal.

In the C programming language, the form feed character may be represented as '\f'.
