Hi jamesnvlss, when you say it only prints half, is that because the content is too long for one page and Firefox doesn't print the second page, or Firefox leaves part of the page blank, or some other situation?

There are numerous layout rules site authors can use which look perfectly fine on screen but which Firefox does not print correctly. Figuring out a solution or workaround may require diving into the details a bit.

Hi! Thank you for responding!

The content is long so that may be the issue. But it also seems that it is leaving part of the page blank, if that makes sense.

Okay, help me visualize it.

For example, one classic printing problem is that the author used a style rule that makes Firefox think a block of text is unbreakable. Firefox will move it to its own page (leaving part of the first page blank) and if it doesn't completely fit on the second page, the end of the content will run off the bottom of the page.

What I'm printing is called a trustee report. The trustee report, once finalized, is viewed in blocks, one right underneath the other. Today's particular report has a total of fifteen blocks (it varies each day) and each block contains fifteen lines each (this does not change).

When I printed today's report for example, from Chrome, it printed all 15 blocks.

When I printed it from Firefox it only printed six of the blocks.

I assume Firefox printed six consecutive blocks and then none of the rest.

Is it a page you can reload, i.e., it's stable once you've finished building the report? In that case, you could try my experimental extension. One of its functions is to change the layout rules that create unbreakable blocks so Firefox can paginate those parts of the page.

https://addons.mozilla.org/firefox/addon/printable-the-print-doctor/

Yes, Firefox printed six consecutive blocks and then none of the rest.

I can reload but I get this message:

"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."

I've added your extension and I see its icon in the toolbar -- how do I use it?

To modify the displayed page, click the icon in the toolbar. Then on the panel injected into the page, click the "Override unbreakable display types" button.

Didn't work. :(

@jscher2000 -- Thank you for your time though! I really appreciate your responses and willingness to help! Thanks again!

I just discovered my co-worker has not updated to Quantum and is running an older version of Firefox (54.0.1) and when she prints the report it prints everything in its entirety.

This must be a Quantum issue or an issue with our site not working well with Quantum.

Same result still, that only the first six blocks print?

There have been a lot of changes between Firefox 54.0.1 (June 2017) and 65.0.2 (February 2019), so it's hard to say which one might be responsible or whether there is a way to address it with a settings change or other workaround.

Yes, same result, even after using your extension as instructed. Oh well, I guess it's a Quantum bug. Or perhaps it's our web site that doesn't work well with Quantum.

Thank you again!

It's possible the site uses some more advanced CSS that didn't work in Firefox 54, so the issue didn't arise until Firefox started implementing those new style rules. Partially implementing, I guess I should say.

Also having a similar issue with Quantum. Last page of a multi-page print out will not print, but will print in Edge or Chrome. I have checked the CSS changes. Switched to using a bootstrap 3.4.1 css, with the same problem. Also tried some @media print css methods to try and solve the issue, with no success.

Print preview also is missing the last page. HTML is a table with a lot of rows.

Any solutions found?

Hi xenial, can you share a link to a page that demonstrates the problem?

It is not a public site, but here is a sample page. Quantum prints 6 pages, missing the 7th. Chrome prints all 7.

Thanks. I can't replicate the problem. Both preview and a PDF printout have all 7 pages.

I tested in my regular Firefox profile, and also in a new test profile. (This is on Windows using Arial; I don't have either of the Helvetica fonts, if that matters.)

After skimming through it, I can't see a reason for it to fail to print completely.

What about printing settings. 100% scale, and margins, headers/footers the same? I am also on Windows. Could it be the printer driver for the printer affecting it, since Quantum uses the windows print dialog?

I did some more testing, and found that it is the 100% vs Fit to page that is the issue. If I set to fit to page, it is correct. At 100% it is missing a page. I also tested multiple versions of Firefox, and this is an issue since Version 52 to current. Before 52, like question owner noted, it is not an issue. For now, I can set everyone to use Fit to page for zoom and see if that solves it. If there is a solution to prevent this, let me know if you find anything.

Aha, yes, I have the default of Shrink to Fit set. At 100% scaling, I lose page 7.

It prints fine (taking 8 pages with large margins) if I delete this inline style rule:

       @page {
           margin: 30px 30px 30px 30px;
       }

or change it to 0.5":

       @page {
           margin: 0.5in;
       }

(Chrome also prints on 8 pages with either change.)

Maybe Firefox doesn't like pixel measurements for print margins?
