Sorry to see that this didn’t get a more prompt reply. I don’t get a preview in the Mac desktop application, or from Safari, but printing from Chrome gives me a preview.
However, I just noticed something odd. If I use the Command-P hotkey in Chrome, I get the same preview-less dialog that I get from the desktop app and Safari. If I use the menu option, though, I get the dialog with a preview. Safari’s Print menu option also brings up a different dialog that has what I believe is supposed to be a preview, but it’s mostly blank, only one page, and completely different than the preview-enabled dialog in Chrome. Very strange.
Long story short: try printing from Chrome using the menu instead of the hotkey. :slightly_smiling_face:
