DOS Form Feed Character - ^L (ASCII 12)

When printing from DOS's redirect, the printer does not always eject the
page, this is because the printer is waiting for the Form Feed (FF) character.
The following is an example of how you can implement a FF with DOS's
native code. There are also third party utilities which can do this for
you. This is useful when using DOS's commands within automated batch files
that require the use of a printer.

Create a file named EJECT by typing COPY CON EJECT at the DOS prompt and
pressing Enter. You'll get a blank line. Press Ctrl-L, then Ctrl-Z (the
DOS end-of-file character), and then Enter. DOS will respond with the
message "1 file(s) copied."

Now create a batch file and call it PEJECT.BAT by typing COPY CON PEJECT.BAT
at the DOS prompt and pressing Enter. At the blank line, type
COPY d:\path\EJECT LPT1 (assuming your printer is connected to LPT1) and
press Enter. Then type Ctrl-Z and press Enter again to create the file.
