Recently, I think since updating to 78.0.2, after pressing the Print button on the webpage it takes 10-20 seconds for the print dialogue box to open, rather than opening instantly. This seems to be the case for all websites I have tried. However, if I select Print from the File menu or use Cmd P, the dialogue appears instantly. I am using Mac OS 10.12.6. Please let me know if there is a setting to change to prevent this printing delay. Also, there is no delay in the print dialogue opening if I use a different browser (Chrome).
