Unattended Flow Unable to Click on Browser Icon.

I'm working on a flow to download a report from a website. After setting the report parameters the only option is to click a printer icon, print to PDF and save as. Works great in attended mode but when triggered by cloud flow in unattended mode the automation fails to get the UI element of the and errors out. I'm used to troubleshooting these unattended errors, but my normal tricks are not working. All the other UI element interactions work just fine in unattended. Since it's unattended I only have error screenshots to go off of. It's unclear if the failure is in the clicking of the printer icon or if the "print to PDF" screen is not popping up.

So far, I have tried:
- using the move mouse to image and click instead of click UI element.

- validate the screen resolutions are properly forced and the same in both modes.

- All the permutations of changing the UI elements and screen selectors I can think of.

Let me know if any of you out there have some ideas on what to try next to get this thing working.

Hi, this is a common challenge when automating print dialogs in unattended mode. Here are a few things you can try:

Use “Send Keys” Instead of UI Click

The print dialog often behaves differently in unattended sessions.
Try sending the keyboard shortcut (e.g., Ctrl + P) to trigger the print window instead of clicking the printer icon.

Add Delays and “Wait for Window”

Insert a delay after triggering the print action.
Use Wait for window or Wait for UI element to ensure the print dialog is fully loaded before interacting with it.

Switch to “Print to PDF” via System Dialog

If the browser print dialog is causing issues, consider using the system print dialog.
You can open it with Ctrl + Shift + P in most browsers and then automate the PDF selection.

Validate Unattended Session Settings

Ensure the unattended session has:
- Same resolution as attended mode.
- Display scaling set to 100%.
- Printer drivers installed (including “Microsoft Print to PDF”).

Use Image Recognition as Fallback

If UI selectors fail, use Move mouse to image and click for the print button and the “Save” button.
Make sure the images are captured at the same resolution as the unattended session.

Alternative Approach

Instead of automating the print dialog, check if the report can be:
- Exported via URL parameters or API.
- Downloaded directly as a file without printing.
