Web AppBuilder printing legend symbology discrepancy

[asiegel_AWWD]

I'm using Portal for ArcGIS (10.5) to create a Web AppBuilder application for printing. I created custom printing layouts and published as service. One layout is 8.5''x11'' (Layout 1) and the other is 12''x15.52'' (Layout 2).

The symbols in the legend of Layout 1 appear fine, but the symbols in the legend of Layout 2 do not appear correctly. See examples below. Does anyone know what might be causing this issue?

This issue used to occur with an ArcMap based custom print service published to AGS.  I don't know if the same bug applies, but you had to set the default printer on the server machine running the printing service to be larger than the largest custom print size in your app.  I will try to find the ArcMap page showing this bug and how to fix it.  Maybe you can perform a google search for a similar issue with a Pro based custom print service.

I have had this support article fix in place for this issue for many years now in the AGS environment.
