Adjusting print margins on safari
I'm using MacOs Mohave version 10.14.5 and browsing the web using Safari version 12.1.1. When I try to print a webpage, the left margin is very small and the top margin is so small, text is often cut off. How do I adjust the margins? I have tried the following: Go to print; go to papersize & choose manage custom size; then created a new custom size that is 8.5x11 with 1" margins all around. I still get the same tight margins regardless. Help please!
