I'm trying to write an error handler, since our printer doesn't do anything
useful (i.e. it just doesn't print the page) when an error occurs. According
to my interpretation of the red book, page 53-54, there is a special dictionary
called $error that contains information about the most recent error. But when
I run the file below in xps, I get 'undefined in operator load'. And it won't
print either. So I'm wondering how to access this dictionary $error, or
alternatively, how to find the name of the most recent error and the operator
that generated it. Thanks for any help/advice that you can give.

According Adobe has an error handler on the file serverAdobe has an error handler on the file server// Adobe has an error handler on the file server. Mail a note to ps-file-server@adobe.com with the words send help then mail another note to the server for send index. You will then have the information you need to access the server and grab the error handler. A much improved version was posted to the net some time ago. Cheers Woody
