L.print.provider ignores my configuration parameters

[ClaraIV]

I want to print a map in Leaflet using the Geoserver Print Module, built on Mapfish. I configured the .yaml file and I am specifying the parameters to be used in the request as below:

var printProvider = L.print.provider({
capabilities: printConfig,
url: "http://localhost:8080/geoserver/print",
method: 'POST',
autoLoad: true,
dpi: 150,

legends: true,
geodetic:true,
outputFormat: 'pdf',

pages: [{center: projcenter,
       scale: 5000000,

       rotation:1}],
customParams: {
          mapTitle: 'XYZ,
          comment: 'xyz'
      }
});

The parameters seem to be ignored, the map is always printed at the same scale(which is listed in .yaml) and does not take into account the scale I set, or the rotation.

pages:[{"center":[2782987.2698318395,5780349.220256353],"scale":2576870,"rotation":0}]

I need help understanding why is this happening and how can I make it listen to my configurations?

The request being sent to the server is here: POST XHR

Hi, I'm sorry but I don't have time at the moment to provide support on this plugin. If you find a resolution for this issue feel free to send me a PR.

Hi,

I don't know how to send you a PR, so I'm writing here.
Apparently this has to do with L.Print-src.js file where the scale computation is defined (as well as the legend one).
I noticed that for me the scale was always computed at half the screen size so, in order to fix this, I multiplied by 2 the scale in the formula. It's a workaround not a solution but now I get correct prints.

I would really appreciate your input on my second question, about the Legends?

Thank you.
