Here, for example, a solution was presented in this German forum. this should be something that suits your needs. I don't have a simple solution like you might want. I don't know of any extensions that can do this either.
Maybe someone else here knows something better...

I appreciate the info but this solution just triggers the browser print screen.

This works but is bulky.... Is there a way to only display #main_content instead of hiding everything?


@media print {
#container_bottom1_modules, #container_header {display: none;}
}

Hi Mark

Would you have a URL to an example of your page?

Hi Ciaran,
It is used in a private intranet.

We are using the Riley template - J4

media print / display: none seems to be the way to do it.

Just wondering if there was better way.

The print function in J3 made it easy, as they just want to print the content. Odd they removed it in J4.

Thanks,
Mark

Hi Mark

A slightly simpler alternative to your CSS would be something like the following...

body > * {

    display: none;

}

#container_main {

    display: block;

}

So here you are hiding everything and then displaying the main content area.
