Yes the screenshot I provided was from IE.
If you are trying to automate the window that pops up with CTRL + P, the window works with Active Accessibility UiFramework.
I think I understand what you mean now, you are saving web pages as PDFs then searching the PDFs for certain text? In that case, after saving the PDFs, you can use the PDF Activities from UiPath.PDF.Activities package to extract the text and search within the text.
Another way you could do this is save the webpage as HTML and then convert the HTML to plaintext string, and search the string that way.
Edit:
Or if the data you are searching for is structured, you could try using the Data Scraping Wizard.
Kind Regards
