>What is very important is that I have an exact count of all the rolls produced, so the production controllers are aware of them, and the weigh station operator has to get the weights for each and every roll?

I'm assuming your client doesn't want to spend more on hardware, otherwise, you could get some of Gates' wunderbar "writing tablets" ...

As an alternative, you could print a "work/job" package with all the appropriate blanks that a floor worker fills in as he completes the job. Later, the worker or a "clerk" could enter the completed package into the work station. The "package" on the work station should look the same as the "hard-copy".
