I am working on ThingWorx 8. The problem is that I have a mashup with many "value display" widgets contained in another mashup. When I try to print the webpage from Chrome or Edge (ctrl+p) it will never load the preview and if I close the dialog box then the page will freeze or crash. If I remove the widgets from the contained mashup, but keeping the widget that containes it in the other mashup, it works fine and load the preview.
I also tried using a print widget from an extension but is the same.
In some cases where another mashup has similar characteristics this does not happen and that seems unusual.
If any had a similar issue before I'd appreciate hearing from you.
Since you only have the problem with the one mashup, is there something regarding the design of that mashup that is causing the issue? Do you have any performance problems with that mashup? It may be necessary to address any performance issues to resolve the printing issue.
You indicated you were running ThingWorx 8. Can you be more specific? 8.0, 8.4.5, 8.5.7? Do you have a ThingWorx 9 server, you could test it on?
