I have already created a blueprint, which is also valid for most other reports (except generic numbered reports like PO,SO, Invoices etc
https://blueprints.launchpad.net/openobject-server/+spec/print-screen-defaults
It is really almost impossible to "work" with the current reports (Example most stock reports) as many/most of the elements described in the blueprint are missing.
After a while we found our self with numerous pages and without making an immediate hard copy of the screen and writing the context (or what we believe the context could be) manually on the paper we just had to throw everything in the waste basket, because nobody new any more why/when/what was the print request.
Even if it is difficult to accomplish a nice and comprehensible layout for context it is mandatory for successful implementation.
Pls ASAP.
as years go by ....
