763870 - HTML table with border are not printed correctly

Status: UNCONFIRMED

(Core :: Printing: Output, defect)

Description

Attachment: ffmacprint.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/534.57.2 (KHTML, like Gecko) Version/5.1.7 Safari/534.57.2

Steps to reproduce:

I printed the attached document via FireFox 13 on Mac OS X 10.6.8.


Actual results:

The black border disappears when printed.


Expected results:

The black border should be printed as displayed.
If you increase the border size to 3px, it starts to appear (border: 3px solid black;).

[You might argue that even the display of black border doesn't look right...]

When you want a document to be printed correctly, you should use "pt" instead of "px" units.
e.g. 0.5pt for a thin line.

Pixels on printers are very small, and a 1px line usually does not show up at all.
This is more a defect of the printer than a bug in the browser.

If you like, you can use a separate printing stylesheet that overrides the border width
when the document is printed.

Rob, "pt" does not help much. On this demo (http://fiddle.jshell.net/w1f0bhtw/14/show/light/) I used 1pt border and it still disappears on 2nd page at the top. Increasing it to 1.5pt helps the top border, but other borders are too thick now. I think the problem in in a way how FF processes "border-collapse: collapse", see bug 307330 and bug 484258.

That is a different bug!   I previously reported Bug 924172 which now appears to be similar
to Bug 307330 (borders incorrect on multipage tables printout when border-collapse is used).

This bug report says that any borders disappear when printed, that is cause by the 1px width
which is too thin to be visible on printout.
