Reproducible: Always Steps to Reproduce: 1.Open the attached link 2.Launch the print preview in landscape mode (no margin, no header and footer). Actual Results: 3 pages : 3 correct tables on 2 pages + 1 thead alone on the third page. Expected Results: 2 pages : 2 tables on the first and 1 on the last. No additional thead.

(I'm using default margin settings, BTW) PORTRAIT MODE: ============== Scaled to 90%: No bug. Scaled to 100%: BUGGY Scaled to 125%: No bug. All three of the above cases show 2 tables on the 1st page and 1 table on the 2nd page. But the "100%" case has an extra 3rd page, just containing a copy of the 3rd table's header. LANDSCAPE MODE: =============== Scaled to 80%: BUGGY Scaled to 90%: No bug Scaled to 100%: No bug Scaled to 125%: BUGGY* Scaled to 150%: BUGGY Scaled to 175%: BUGGY In all the above cases except for 150%, "BUGGY" means there's one extra (unnecessary) page that just has a copy of the header for the 3rd table. The 125% case is starred above because it's slightly different -- it has an extra copy of the _second_ table's header, which is located just before the third table. A reduced testcase would be awesome for helping figure out what's going on here.

Here's a zip of the original testcase, in case it ends up as a broken link at some point.

Wow that's testing man ;-) I'll try to make a minimal testcase if I manage to get some free time. I know my examples are too long. Thanks Daniel !
