esri.tasks.PrintTask won't print WMS layers hosted by non-ESRI servers

AzaveaInc_ — Mon, 11 Mar 2013 12:39:36 GMT

My esri.Map is successfully displaying WMS layers via esri.layers.WMSLayer. Some of the WMS layers are hosted by ArcGIS Server and some are hosted by non-ESRI servers. But when I print using esri.tasks.PrintTask, only the WMS layers hosted by ArcGIS Server are visible. The WMS layers hosted by non-ESRI servers don't show up.

Has anyone succeeded in printing a WMS layer which is hosted by a non-ESRI server?

Hi Rick

I enclosed a little code for WMS Layer printing. I used an esri.request print template from proxy firing parameter web map as JSON.
This is could be implement to Print Task mode and also you must setting the proxy page to test my simply code. Beside that I'll give
you PDF sample as result from this simply code.

Note: I add WMS layer from non ESRI servers

Re: esri.tasks.PrintTask won't print WMS layers hosted by non-ESRI servers

I love your solution, great work!

I tried modifying it to my own needs, using the WMS service from Open Weather Data. The layer is displayed correctly (look for the black lines, the Isobars), but aren't printed. Any thoughts on why that happens?
