LabVIEW 26Q1 Browser Control - HTML Print to PDF

‎02-05-2026 12:54 PM

Is it possible to print HTML to PDF from the new browser control like you could with the Webview2 control (sklein)? Interestingly if you feed the new control a pdf it shows a tool banner with print a button, but I don't see a way to turn the tool bar on/off programmatically.

 

System: Win11 VM, Microsoft Edge. (Adobe Acrobat, MS Office not installed)

There is very little information in the help except it's a browser!  What is it based on? Where is the cache ? Does it cache? This is important if pages are partially dynamic.

Hav you tried ctrl+p? Maybe as a hack, try to give the control focus and then send control+p then enter

To print from the new browser control call "window.print();" through an invoke node > Execute Javascript.

To control the toolbar display of a pdf in the browser control, the pdf file needs to be loaded from an html file using iframe with the "toolbar" option. It doesn't work as sting constant.

Example toolbar off:

<!DOCTYPE html>
<html>
<iframe src="c:\Project Files\Enchiladas.pdf#toolbar=0" width="100%" height="978">
</html>

 

Example toolbar on:

<!DOCTYPE html>
<html>
<iframe src="c:\Project Files\Enchiladas.pdf#toolbar=1" width="100%" height="978">
</html>

This is really useful information thank you! Have you found any documentation from NI or is this just general web and JavaScript stuff? 

Thanks!!

There are a few LabVIEW examples in example finder, but not for these specific questions. It was mostly Javascript web searches and trial and error.
