[OpenLayers-Users] pdf export: why the request for tile dimensions of 625x458

[Robert Buckley]

Hi,

Thanks for the reply.

according to my research it is possible. gbrun managed to get this working with TMS services with the help of Matt Prior documented in the link below. The proof is in the online map here

Hi Robert, 
This may not be entirely helpful however I don't think that mapfish supports printing from a tile cache. The way it works normally is that it sends the request straight to the wms server which can obviously respond to the size it requires. 
The reason you are getting that tile size is because that's the size of the window you are trying to print (I presume). 
As a test, if you were to point your layer_topo straight to the wms does printing work?
