print preview and pdf display

[Trung Pham Quoc]

Hi team,

I am working on a problem on the print preview. My team is currently working on a Tor feature in premium and we have some trouble with the print preview, as  it never receive the pdf files created by the renderer. I cannot find in code where the pdf is displayed by the browser process so I cannot check whether the pdf file have been received by the browser or not. Do you guys have any suggestion where I should look for.

On the browser side, the PDFs used for print preview are stored in
PrintPreviewDataService.

Within Print Preview itself, you can use DevTools to see the URL of the PDF being loaded (which, as Lei mentioned, comes from PrintPreviewDataService).
