No, there is no way for you to directly communicate with the user.

Keep in mind that your filter may not be running on the same system
as the user, or the user may not be logged onto the console when the
job actually gets printed.

About all you can do is use STATE: messages to make the printer queue
icon bounce in the dock so that the user can correct the problem, but
your driver will need to monitor the printer to know when to continue.
