- FFLFNP.COM -- RAM RESIDENT FORMFEED AND LINEFEED PROGRAM

- This program is not warranted in any way. The user assumes all risks of
- using this program.
-
- Instructions
- ------------
-
- Press [Alt - *] (PrtSc) to Send FormFeed Character to Printer
-
- Press [Alt - /] to Send LineFeed Character to Printer
-
- The program checks to see if the printer is ready before sending any
- characters to the printer. If the printer is not ready (off, off-line, or
- not connected), the keystroke is canceled, and the computer will beep.
-
- If [Ctrl-PrtSc] or [Shift-PrtSc] is pressed, the program checks to see if
- the printer is ready. If the printer is ready, the program calls the
- standard DOS PrtSc functions. If the printer is not ready, the program
- will beep, and cancel the keystroke, so that the computer will not hang.
-
- Notes :
-
- 1) With most printers and some external print buffers, the program will
- work as described above.
-
- 2) Some external print buffers (and a few printers) may not relay the
- printer ready message back to the computer properly. They will always
- report that the printer is ready, whether it actually is or not. In
- this case, if any of these keystrokes is pressed while the printer is
- not ready (turned off or keyed off-line), the computer will hang. If
- this occurs, the computer will un-hang as soon as the printer is
- turned on or keyed on-line.
-
- 3) Computer hangs should not occur with internal print spoolers. Either
- the computer will work as described above, or the character(s) to be
- sent to the printer will be retained in the print spooler until the
- printer is ready.
-
- 4) Many keyboards combine the * key and the PrtSc key. For this type of
- keyboard, the program will work as described above. Some keyboards,
- such as the new AT style keyboard, separate the * key from the PrtSc
- key. For these keyboards, the DOS PrtSc functions will work as
- descibed above, but pressing [Alt-PrtSc] will do nothing. For these
- keyboards, the [Alt-*] keystroke must be used to send a FormFeed to
- the printer.
-
- 5) The program can be installed at any time by entering its name (FFLFNP)
- at the DOS prompt. Or, its name can be included in your AUTOEXEC.BAT
- file, so it will be installed whenever you boot your computer. The
- program checks to see if it has already been installed, and will not
- install itself more than once.
-
- 6) The program size is 896 bytes. However, the RAM-resident portion of
- the program is only about 430 bytes.
-
- 7) The program has been tested extensively, and no problems have been
- found. However, it has NOT been tested with many other RAM-resident
- programs, such as SIDEKICK. Programs that redefine the keyboard, such
- as STATGRAPHICS, will cancel the operation of this program while they
- are in operation, but will return control when you exit. If anyone
- using this program discovers any problems, please notify the author,
- so that an attempt can be made to solve the problem.
-
- 8) Requires DOS 2.0 or later.
