That all makes sense - thanks.

I actually did that a couple of days ago when the printing returned the
latex source rather than the postscript - I was able to run that by hand
and it seemed to process fine. The resulting postscript looked OK and
there were no errors that I could determine.

I have re-done it now (having removed the 1st and last lines to allow
delivery of the latex to the user) and here is the full output:

This has produced a .dvi file and I can convert that to postscript with

It is version 0.300.2.

Great - we can rule that out.

Really, we need to get the postscript/pdf output working. Not being able
to generate printable invoices is a stopper. If there's any extra
debugging or similar that we can enable to track down why the latex
process is giving these failures that would be great.

In the meantime I will go through the templating guide and see if there
is anything in there which I can use to solve this.
