Triaggers : - for a bug that reports bad page splitting / missing pages in print or print preview, and you have no idea if it's a dup of an existing problem, mark as blocking this bug - if you strongly suspect it's a dupe of a problem in the list of those blocking this bug, mark it as depending on *that* bug. Leave a comment on the bug that if solving the depending bug doesn't solve the problem, the bug should be changed to blocking this one - if you have *demonstrated* it's a dupe of an existing problem, close it by duping to that bug. But add a comment to the duped bug with the url of the problem. In the first two case, please try to extract a reproducible test case from the page. If you don't have much time, don't try to minimize it, but *do* try to save it as a workable test case somewhere. If this is not done, the page will very probably have changed by the time someone wants to check what the problem consist of exactly or if it is corrected by some fix, and the usefulness of the bug will be reduced to about zero.

Problem is still exists in Firefox trunk 53 version, we can reproduce this problem via try to print this page: http://semantic-ui.com/ - this only one example, but in real I can't print many sites! This is serious problem!

Still reproducible and only prints the first page.

Investopedia also only prints the first page
https://www.investopedia.com/why-value-investing-model-championed-by-buffett-is-broken-4691764

However it does work with simplify page.

That Investopedia one is bug 939897. (They use display:flex on <body> and <main>, and if I override those to use display:block instead, then it doesn't get truncated.)

Same issue for Google Forms (only prints first page).

This URL prints only the first page, seen on 69.0 on Mac OS X 10.14.6 (BuildVersion: 18G95).

ahem, sorry, I just realized this one has a "META" tag. Can someone please educate me what the procedure is here? Should I report this a new bug, and create in that new bug a reference to here, or is the comment here enough?

hey Florenz, I believe the comment here is good enough.
If you have the time to investigate further, and then you realize the problem comes from another root issue we haven't uncovered yet (so isn't covered by dependent bugs), then a separate bug would be useful.
Thanks for your contribution :)

This URL prints only the first page, seen on 69.0 on Mac OS X 10.14.6 (BuildVersion: 18G95).
https://help.sap.com/doc/00f68c2e08b941f081002fd3691d86a7/2019.19/en-US/11b4e5ff76eb4747bc255d7037be1f01.html

FWIW, when this page is shown in Print Preview mode it only indicates that one page is to be printed. In other words, page 1 of 1. This same behavior was note in IE11 and Firefox version-de-jour on my work station. I would suggest that this behavior may be normal for this page (i.e., the author has coded the page intentionally to prevent printing the entire content from the web perhaps because they offer it for sale separately). Just an observation.

After seeing the last comment, I confirmed the same behavior of that page on:

MacOS High Sierra 10.13.6 (17G8030) with Google Chrome 76.0.3809.132 (Official Build) (64-bit)
MacOS High Sierra 10.13.6 (17G8030) with Firefox 69.0 (64-bit)
MacOS High Sierra 10.13.6 (17G8030) with Safari 12.1.2 (13607.3.10)
McaOS Mojave 10.14.5 (18F132)​ with Safari 12.1.1 (14607.2.6.1.1)
Windows 7 Professional SP1 with Google Chrome 77.0.3865.90 (Official Build) (64-bit)
Windows 7 Professional SP1 with Firefox 69.0 (32-bit)
Windows 7 Professional SP1 with Firefox 69.0.1 (32-bit)
Windows 7 Professional SP1 with Internet Explorer 11.0.9600_19431

So it really looks like the page really does something that hoses printing on all of the above web browsers. It is still a bug that this behavior occurs, but -- like the bug that Teardrop attack of several years ago exploited -- it seems to be extremely widespread (although fortunately of much less severe impact).

yes, SAP is a software vendor, but no, that page is free to view anonymously, no logon credentials required

reported it as SAP incident 537216 / 2019 (in a system for SAP customers) , and I will ask directly if that is intended behavior or not. Also mentioned this bug in the incident, as soon as I hear something back I will post it here.

That SAP page simply has all of its content inside of an overflow:auto element (i.e. a scrollable element) which is sized to fit in the viewport (top:91px; bottom: 0), which in the case of a printed document is the first page. When viewed in a browser, you can reach all the content via scrolling that element, but of course there is no scrollbar in the printed output.

So indeed, browsers are all printing it "correctly", and SAP probably wants to add a "print" media query to turn off that overflow:auto styling (and perhaps some other styling).

In any case: let's please not have further discussion/investigation of individual issues on this bug, since this is a meta-bug. Best to spin off individual bugs per-issue so that this bug's comment-thread doesn't become a giant wall of different investigations. Thanks!

when using "cups-pdf" or "save as adobe pdf" (with adobe acrobat x pro) to print this site here
https://www.middleeastmonitor.com/20190403-israels-politicians-are-chickens-we-need-to-shake-up-the-system-says-hadashs-jewish-candidate/
on mac osx 10.6.8 and with camino browser
only page 0/1 is printed the rest is truncated.

Sorry if this is the wrong place to report this, but I don't know if it is a duplicate of any of the other print truncation bugs. Regardless, I hope it is a useful additional reproduction. This page: https://boardgamegeek.com/thread/1855931/12-dice-are-so-light-and-portable-you-can-always-h looks correct when using dev mode to preview as a printed document, but truncates after the first page (printing the first page, and a nearly empty second page) when printing to a PDF (and presumably when printing in general, although I haven't tested that).

Oops, I should have checked my pending updates. I was on 77. On Firefox 78, the page also does not print properly, but in a totally different way. Now it seems to get truncated in random places, and chop out assorted parts of the pages, while printing other pages as blank. Still, the changes suggests that this issue is being worked on, which I really appreciate. Again, I hope that the above link is a useful test case for you.

Why this comment marked as spam. I was facing the issue. But may be there was problem with my profile. I have changed my profile & also updated to the current version. Now Its working good.

I didn't want to send it to an actual printer, when I selected "save to file" a 28 page PDF was created. What happens if you save to a file? If you only get only the first page try in Troubleshooting mode or a new profile.

Thanks for your genuine feedback & support.

Sorry -- looks like somebody misunderstood your comment and thought you were a spammer; people post links with all sorts of weird ads on bugzilla, and your "passive-income-ideas" link probably looked like that, at first glance.

In any case, I've removed the spam annotation from your comment.

But may be there was problem with my profile. I have changed my profile & also updated to the current version. Now Its working good.

Glad to hear it! I tried the site that you mentioned and didn't see any missing content, so I suspect all is well now.

In the future: if you or anyone else encounter a bug of this type, please don't add a comment here -- instead, it's best to file a dedicated bug for your issue, using the "New/Clone" button at the top of this page, with the "...that blocks this bug" menu entry.
