Question
Each time I run the Scale Print Jobs I receive the following error message in the ScalePrint.BAT command Shell,.. what is causing this?
Answer
The error message in the Python Command Shell relates to at least one LAYER failing to print. If you check the Error Log for this print job in the MTPrintFiles folder the error log will likely list the layer causing the issue.
In many cases this will be a WMS layer which for some reason cannot be loaded into OSGEO4W and so the print job fails.
