[OpenLayers-Users] Mapfish/Geoserver print issues with GeoExt

[Brad Bordine]

I am trying to include a legend and a div containing some tabular data 
to the Geoserver print plug-in aka mapfish print. While I am having some 
issues with rendering my tiles from my remote server (the webapp 
co-hosted with  geoserver does not have this issue) my main concern is 
that the legend graphic is rendered as tiny, and because we have 
rule-based legends, a tiny icon will not work. The is a default scale 
argument in the documentation but I see no means to specify the scale to 
render the legend icons. I will include the yaml and some configuration 
code snippets.
