Column count does not work with css in PDF

I will used column-count: 2; and columns:2; in html and that html convert in pdf format.

I can use below npm package

npm install -g html-pdf

in pdf column-count: 2; not working

and I can try also this

@media print{
    .newspaper {
        -webkit-column-count: 2;
        -moz-column-count: 2;
        column-count: 2;
        -webkit-column-gap: 20px;
        -moz-column-gap: 20px;
        column-gap: 20px;
    }
}

but it's not working.

My requirement is first column fill up then start second column this is my main requirement.

Thanks
