I have a HTML report, which needs to be printed landscape because of the many columns. It there a way to do this, without the user having to change the document settings?
And what are the options amongst browsers.

Quoted from CSS-Discuss Wiki
The @page rule has been cut down in scope from CSS2 to CSS2.1. The full CSS2 @page rule was reportedly implemented only in Opera (and buggily even then). My own testing shows that IE and Firefox don't support @page at all. According to the now-obsolescent CSS2 spec section 13.2.2 it is possible to override the user's setting of orientation and (for example) force printing in Landscape but the relevant "size" property has been dropped from CSS2.1, consistent with the fact that no current browser supports it. It has been reinstated in the CSS3 Paged Media module but note that this is only a Working Draft (as at July 2009).
Conclusion: forget about @page for the present. If you feel your document needs to be printed in Landscape orientation, ask yourself if you can instead make your design more fluid. If you really can't (perhaps because the document contains data tables with many columns, for example), you will need to advise the user to set the orientation to Landscape and perhaps outline how to do it in the most common browsers. Of course, some browsers have a print fit-to-width (shrink-to-fit) feature (e.g. Opera, Firefox, IE7) but it's inadvisable to rely on users having this facility or having it switched on.
You might be able to use the CSS 2 @page rule which allows you to set the 'size' property to landscape.
You can also use the non-standard IE-only css attribute writing-mode
div.page {
writing-mode: tb-rl;
}
I tried Denis's answer and hit some problems (portrait pages didn't print properly after going after landscape pages), so here is my solution:
body {
margin: 0;
background: #CCCCCC;
}
div.page {
margin: 10px auto;
border: solid 1px black;
display: block;
page-break-after: always;
width: 209mm;
height: 296mm;
overflow: hidden;
background: white;
}
div.landscape-parent {
width: 296mm;
height: 209mm;
}
div.landscape {
width: 296mm;
height: 209mm;
}
div.content {
padding: 10mm;
}
body,
div,
td {
font-size: 13px;
font-family: Verdana;
}
@media print {
body {
background: none;
}
div.page {
width: 209mm;
height: 296mm;
}
div.landscape {
transform: rotate(270deg) translate(-296mm, 0);
transform-origin: 0 0;
}
div.portrait,
div.landscape,
div.page {
margin: 0;
padding: 0;
border: none;
background: none;
}
}
<div class="page">
<div class="content">
First page in Portrait mode
</div>
</div>
<div class="page landscape-parent">
<div class="landscape">
<div class="content">
Second page in Landscape mode (correctly shows horizontally in browser and prints rotated in printer)
</div>
</div>
</div>
<div class="page">
<div class="content">
Third page in Portrait mode
</div>
</div>
Here's what I came up with - add a negative rotation to the <html> element and a positive rotation of equal abs value to the <body>. That saved having to add a ton of CSS to style the body, and it worked like a charm:
html {
transform: rotate(-90deg);
}
body {
transform: rotate(90deg);
}
The problem I faced is probably the same you have. Everyone here is using CSS to provide it statically, but I had to look for a dynamic solution so that it would change based on the active element without reloading the page..
I created 2 files, portrait.css and landscape.css.
portrait.css is blank, but landscape.css has one line.
@media print{@page {size: landscape}}
in my primary file, I added this line of html to specify portrait.css as default.
<link rel="stylesheet" id="PRINTLAYOUT" href="portrait.css" type="text/css" /></link>
Now, to switch you only have to change href in the element to switch printing modes.
$("#PRINTLAYOUT").attr("href","landscape.css")
// OR
document.getElementById("PRINTLAYOUT").href = "landscape.css" // I think...
This worked great for me, and I hope it helps someone else doing things the hard way like me.. As a note, $ represents JQuery.. If you are not using this yet, I highly recommend you start now.
If you are using React and libraries like MUI, using plain CSS in your React app is not a good practice. The better approach will be to use a style component called GlobalStyles, which we can import from Material UI.
The code will look like this,
import { GlobalStyles } from '@mui/material';
const printStyle = {
['@media print']: {
['@page']: {
size: 'landscape',
margin: '2px',
},
},
};
You might not need to use @page inside the @media print because @page is only for printing. Documentation
The margin will eliminate the URLs, the browser generates while printing.
We can use the GlobalStyles in our App container. Like this
const App: React.FC = () => (
<>
<GlobalStyles styles={printStyle} />
<AppView />
</>
);
It will apply the above CSS whenever we call windows.print().
If you are using other libraries besides MUI, there should be some components or plugins that you can use to apply the CSS globally.
