Have you tampered with the printer driver recently? If not, try to remove it, then reinstall it.
If not, it could be Word 2000. Try to reinstall it by running the setup again. There should be an option to repair or reinstall the previous installation.
I'd be tempted to try the printer driver before Word, because when Word invokes the printer driver through Windows, it crashes. It might be a bad command going to the driver from Word or the driver not understanding and becoming corrupted.
Hope this makes sense.
