Sorry, I should have included that.  The cut down version follows; I
have a few more comments and so forth so I can revisit it if I wish.

I didn't make any attempt to automate the process at this stage, but
will have a play with all the suggestion and see if I can get it to
work.


For reference, this is aimed at printing multiple identical labels in
each batch, rather than distinct content on each label, so I don't worry
about the font size changing between the individual labels in the run or
anything.
