Print orientation is not honored
When using the WebDriver print function, landscape orientation is not honored.
Additionally, when page dimensions are provided, the smaller dimension is always used as the page (PDF MediaBox) width and the larger as the page height, but content gets fit to the width and height as provided. (I'm not sure whether this should be a separate issue, but it may be related.)

curl -s -XPOST -H 'Content-Type: application/json' ${WEBDRIVER}/session/${SESSION_ID}/print -d '{"pageRanges": ["1"], "page": {"width": 20, "height": 5}}' \
| jq -r '.value' | base64 -d > test_page_size_width_height_reversed.pdf
curl -s -XDELETE ${WEBDRIVER}/session/${SESSION_ID} | jq
When using chromedriver, the script yields pages oriented as expected.

Thanks for filing! Marionette expects a landscape boolean parameter for some reason and is not following the spec. I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1791819
When I print bing.com, it seems background also not effected
The background is handled by https://bugzilla.mozilla.org/show_bug.cgi?id=1783086. I'll update the summary so that we can keep both covered here.
@whimboo @juliandescottes are there any news on the potential fix for the issue?
Sadly we won't have the time to work on it within at least the next month. There is a change for early 2023. If it has a high priority for you, we would be more than happy to mentor you in case you want to fix it yourself.
@whimboo that would be great, I'd love to fix the issue. what would be the best place to start from?
That sounds great! May you be able to join us on Matrix via https://chat.mozilla.org/#/room/#webdriver:mozilla.org? You can find me there and I'm happy to chat and explain the first steps.
