Thanks for the responses. Peter Chubb suggested that I was shrinking the scores twice which was something I had begun to suspect. I changed the 'A4' to 'A3' in my script and my PDF viewer shows something a bit different from what I was getting before. I'll have an opportunity to try printing it tomorrow. Using the pdfjam commands Peter sent produced very odd results at my end. Maybe there was something missing or something implied which I missed. Thanks for the GUI tip from Raphael Mankin, but I'd rather have a script do this. Alexander Kobel's point about pdfjam is also good to know.
Thank you all. If I haven't fixed it with your suggestions I'll try again.
