How to remove page margins from the print version?

Question

css

Guys, such a problem. I want to print a page without margins. Now the print version looks like this: https://yadi.sk/i/QdyK5xLvlVyAlg The margins in the browser are set by default and as a result there are margins of 1 centimeter. Is it possible that IN THE DEFAULT SETTINGS there are no such fields? And the default settings are the margin settings of the browser itself, or do you mean the default settings for print styles?
Now the print styles are as follows:

@page { 
    margin: 0 !important;
    padding: 0 !important;
    position: relative;
    page-break-inside: avoid;
    size: 21cm 29.7cm;
    zoom: 1.0;
  }

body, html indents - also reset to 0, did not help.
