Your link does not give any solution. There the question is related to a GUI craeted with AppDesigner. This question is about WebApp GUI. The solution given in your link does not work for WebApp GUIs.

You can use exportgraphics(obj,filename) to write a graphics object obj to filename on the web app server temporarily. Afterwards call web(fileName) to display and/or download the file in the browser.
function PrintButtonPushed(app, event)
fileName = 'graphic.pdf';
% or query for filename:
% [fileName, ~] = uiputfile('*.pdf');
exportgraphics(app.UIAxes, fileName)
