Hi @TheGreenOrange,
By default, the PrintingTools service in ArcGIS Server uses the value "Title" of the parameter from the web map JSON to name the output file (e.g.,Title.pdf ). If this parameter is not provided, the output defaults to untitled.pdf.
You can create a custom layout in ArcGIS Pro or ArcMap and add a dynamic text element for the map title
<dyn type="layout" property="metadata" attribute="title" emptyStr="DefaultMapTitle"/>
Share custom layouts for printing from ArcGIS Pro: https://enterprise.arcgis.com/en/server/latest/publish-services/windows/tutorial-publish-additional-...
Export Web Map (Server):https://pro.arcgis.com/en/pro-app/latest/tool-reference/server/export-web-map.htm
You can also use Web AppBuilder or Experience Builder: Print Widget allows users to enter a title, which becomes the file name
Hi, that dynamic text element doesn't work. The File Name is still blank by default. This is in the javascript 4 environment. It works fine in js 3
