Someone else had this same problem before, but there are no answer to the problem then.
I have installed batch_print, it seems to be OK as far as trying to print something. When I select dates and press submit i get following:
1054 - Unknown column 'o.orders_prefix' in 'field list'
select o.orders_id,o.orders_prefix,h.comments,MIN(h.date_added) from orders o, orders_status_history h where o.orders_id in (4) and h.orders_id = o.orders_id group by o.orders_id
[TEP STOP]
Does someone no now what is the reason?
