As you can see, in the "Actual document as printed.pdf", the bottom of the 1st page is missing step 2 even though it appears in the print preview.
Because of this issue, I end up having to print from Chrome to get the complete document printed properly.

The Bugbug bot thinks this bug should belong to the 'Core::Printing: Output' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

jfkthame, could this be a regression from bug 739096?

Hi Avi Schwartz , thanks for the report!
Can you please confirm if this is the website? SO I can try replicating this on my end. Is this also happening when trying to print to pdf from any other website or is it specific to cookbook?

Hi Clara Guerreo,

This seems specific to the website https://thecookbookapp.com/ when printing a recipe by clicking on the Print Recipe button on the recipe page as you can see in the screen capture I will upload next.

So far I didn't run into the same issue with other websites, but in reality I don't print very often.

One more thing. This is not specific to one specific recipe but all of them as far as I can see.

I guess it's possible, though doesn't feel very likely to me. (If Clara can reproduce, maybe she can check whether it regressed, or the problem predates that.)

This looks like an issue of some kind with the margins/page dimensions. Note that the PDF output shows slight clipping of the text on the right-hand side as well as having lost the bottom couple of lines; it's like we've set up the wrong printable area somehow.

The site here appears to require purchase of a mobile app, which I don't have, so can't reproduce & investigate directly, but bug 1721908 sounds quite similar; in that case, Alice0775 indicates that it may be related to the use of relative positioning.

Thank you so much for the amazing Firefox browser. Whenever I am not printing, this is by far my choice of browser.

I am currently using Firefox 101.0 and it indicates that it is up to date.

I have long had this same printing problem across many different websites. Whether text or image, whether printed to Canon MX860, HP OfficeJet 5258, or Microsoft Print to PDF, a small vertical extent is lost at the page boundary. Since Chrome prints reliably, whenever I will be printing from a web site, I must use Chrome, although I prefer Firefox and would really like help see this matter resolved.

I have reset firefox printer settings per instructions here:
https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox

However, the problem persists on my system, and is easily visible when printing that same "fix printer problems" web site.

It is my impression that this is an edge case not shared by most users. I am willing to provide more detailed information or examples if that would be helpful. Also I am willing to experiment, although the limits of my knowledge require hand holding such as, right click on web page, select inspect, click on style editor, insert <some text>, did this fix problem? etc.

I would attach an example picture from the indicated website, but I am unable to understand how to do so.

Thanks again for all the incredible effort required to support and maintain Firefox!
