In my opinion this should still be in the control of the end user. It's their printer and paper - they probably know best.

@media print {
    @page {
        size: auto;
    }
}

for the site and click the extension's icon again to save it.

Then, reload the page if it's still open. From then on, you should be able to print with the orientation you want for the site.

In my opinion, it's https://bugs.chromium.org/p/chromium/issues/detail?id=1098468 that represents this issue (even if it's about "portrait" instead of "landscape"). The bug has been stalled, but someone could comment on the bug and point to this forum etc.

That's just silly that this is even a feature. I see so many ways that this could go wrong. Only makes sense for precisely laying out stuff, which business apps might use - but then they should be using locked down LTS web browsers, not public builds.

also think there's an old post on these forums about this. Will see if I can find it.

Couldn't find the thread on it, but found the bug I was thinking of (and previously commented in it and starred it). See https://bugs.chromium.org/p/chromium/issues/detail?id=1016235. There's also https://bugs.chromium.org/p/chromium/issues/detail?id=1098468.

I found those by searching for https://bugs.chromium.org/p/chromium/issues/list?q=css page size landscape&can=1.

https://bugs.chromium.org/p/chromium/issues/detail?id=1202672&q=css page size landscape&can=1 is another bug that sounds like the issue. But, that one was marked "wontfix" because the user didn't respond.

@media print
{
@page
{
size: landscape;
}

If so, I think Chromium honors that strictly without a way to override it.

To test if it's a problem, delete size: landscape; from the css file (the css is editable there) and try hitting ctrl + p again to see if it then shows the layout drop-down to switch between landscape and portrait.

If you find this is the case, the site needs to fix their css to not force landscape mode.

I found https://ocw.mit.edu/ans7870/SP/SP.236/S09/lecturenotes/drugchart.htm as an example page. (Found that at https://superuser.com/questions/1455052/how-do-i-force-chrome-to-print-a-web-page-in-portrait-mode)

@leacg Yes, Chrome and other browsers do it too.

Here's an example with personal info blotted out. Amazon is portrait. Newegg.ca is portrait. Newegg order invoices are landscape with no option to change it.

Only certain websites do it. Most still have the option to change the layout. And most still default to Portrait. So I'm assuming there's either some intuitive AI settings thingy at work (which should be disabled IMO - just show me all the options) or they've enabled something that lets websites choose what you can and can't see. (bad form, IMO) Generally when you allow websites to decide what you can see - like if you have a mouse cursor, or whether menu and address bars are there, or whether to go fullscreen, etc - some scammer comes along and combines all the features into a way to trick elderly people and computer novices into paying them money. If you give a website some trust or some rope, they'll hang you with it.

I want my print options back so that I can print invoices properly.

Given it is apparently showing Landscape, the panel may be somewhat narrow and you may have to scroll it.

It's an order summary page at Vitacost. Layout starts to appear then disappears. Looks like Opera is having a problem with it.
