Seriously there is a free PDF library - PDFlibLite - that will in 
principle work if you parse the stuff you want using a language like C 
or PHP and then you can write functions to place simple text anywhere 
you want.

I have used it to formulate invoices and the like. Its limited, but its 
solid in what it can do.

yep. been there done that got the T-shirt.

I have a few bits of php library that work up a slightly better 
interface to the Lite library than are supplied.

Its a few days work to do what you want: also you are probably 
restricted to inbuilt PDF fonts ..I cant remember..anyway I used 
helvetica throughout.

Tools are provided to decide the size of strings that you want to print 
so you can do wrapped columns, text centering.right justification and 
the like..but it all gets a bit fraught.


If its any use, heres a waste of bandwidth...

To people who know too much, it is a sad fact
that they know how little is really possible -
and how hard it is to achieve it.
