1721015 - Python Generated HTML Documents Not Printing Properly in Release Version 90.0

Status: RESOLVED DUPLICATE of bug 1720621

(Core :: Printing: Output, defect, P2)

Description

[Steve]

Attachment: GR02_10_Plenum_Init_05162019_160114.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0

Steps to reproduce:

Using Python to generate html file and open in browser for viewing and printing. Has been working for many years through release 89.0.2 until update to release 90.0.

Actual results:

Opens correctly in browser, but prints truncated on right and bottom of document, try using attached document. Just updated all clients to latest Microsoft Updates, including PrintNightmare patches, and Firefox from version 89.0.2 to 90.0. I think I can rule out the Microsoft patch because on machines that I installed the Microsoft patches but did not update Firefox, the printing is still correct.

Expected results:

Print entire page as viewed in browser. Opens and prints correctly in Edge browser.

The Bugbug bot thinks this bug should belong to the 'Firefox Build System::General' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Using Python to generate html file

Can you elaborate on what this entails?
If you can attach an html file that reproduces this problem, that would be great!

Sending this to the print folks.

There is a file attached "GR02_10_Plenum_Init_05162019_160114.html" to my original request. I believe this may be related to Bug 1720621? The file does not print correctly when scaled.

Hello, I've registered because I've run into similar problems with html page printing too, and they appeared in Firefox version 90

I have an example of html page, which is printing fine in Chrome and Edge, but when I use Firefox, the preview and actual results are missing content — missing table borders, partial images, etc., and changing scale from 100% to less actually make things worse.

The contents is missing from the right side and bottom, and table borders too.

According to people who use the system every day, it was printing fine just yesterday, so I believe it is connected with recent release.

I could reproduce the printing issue in Firefox 90.0.
Both documents attached to this bug are now printing properly in Firefox 90.0.2. I suspect bug 1720621 also fixed this, will search for the fix if needed.

Steve, Sergey, could you please confirm? Thank you!

That's correct 90.0.2 fixed this problem!

As for example of mine, it's now printing correctly, thanks, but the table borders are missing in print preview (they are still printing though)

Sergey, in my opinion this worth a separate bug. Thanks!
