Printing the generated page

Question

HTML

After filling in the price list, an html document is generated, which then must be sent for printing and stored on the server. Everything is formed and preserved. The only thing is that I can not find the exact width and height of the block for printing in A4 format. And how to print only a certain block, and not the entire page?

Answer 1

@media print { /* Стиль для печати */
     /*тут вы можете отключить все не нужные для печати блоки*/
    .header, .footer {display: none;}
}

Answer 2

See how it is implemented in bootstrap getbootstrap.com/css/#responsive-utilities-print
