We have a MS-DOS application(coded in FoxPro), and recently had this glitch: the screen menu of the application without reason starts printing in an LPT Panasonic KX-1150 printer. It's a never ending print of all the screens of the application, as if the main output instead of sending it to the monitor, sends it to the printer! It creates a unnamed document with N/D pages and keeps printing forever. We have to turn the printer off and then kill the document in the spool to stop it...

The printer is installed with a Generic/Text driver, and has happened to us both in WindowsXP and Win7. What can this be?

Thanks in advance

What changed? Have you tried using system restore to go back to a date before the problem? –  CharlieRB Nov 14 '12 at 20:27

1 Answer 1

As it's a DOS application, then I can think of only 2 ways in which the output can be redirected:

  1. Something has changed within the app itself. This is totally dependent on the app, and I cannot make any further comments.
  2. The app is started with its output redirected, as in:

APP > LPT1:

As you probably do not start the app from a command line with this redirection, you need to check the batch file that starts it. Right-click its icon and select EDIT, to open it in NotePad. If that looks normal, then my first suggestion is where your problem lies.
