From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:0.9.8) Gecko/20020310 BuildID: 2002041818 When the referenced page is printed to a HP 2100 postscript printer, several of the table cells seperator lines are missing. Incorrect results sometimes present in print preview also, but many times are different. Reproducible: Always Steps to Reproduce: 1.Load the page 2.Print to printer 3. Actual Results: Later records in printout are missing seperators, especially on page 2. Expected Results: Every record (as defined by the Flight Number column) should be seperated by a line and the table formatted consistently. The problem seems to happen only with longer tables, one and two records don't have the problem. Problem is more prevalent on the second page, but not limited to. I had to blank out the text on this page for confidential reasons.

I'm using Mozilla 1.0 RC3 on a PIII 500Mhz PC running Windows 2000 SP2. Large tables (bigger than one page) are printed/print previewed incorrectly. Small tables are OK. As soon as tables get longer than one page printing/previewing is not done correctly. The lines on the second, third ... pages are shown without lines. There are three tables in the attached HTML file. The first one is small enough to fit on one page and therefore printed/previewed correctly. The second and third tables are printed/previewed correctly on their according start page. The following pages are printed/previewed without lines.

Comment on attachment 86384 [details] HTML file containing large tables formatted with CSS When printing CSS formatted tables bigger than one page the table lines (graphics) are missing starting at page 2. The attached HTML-File shows 3 tables of different sizes. The first one fits on one page and is printed correctly. The other ones need several pages and are printed correctly only on the respectiv first page. This can be seen in print preview too.

doe sthis still exist in 1.1beta?

I tried testing it with 1.1b that I personally compiled on Solaris 2.8 (no precompiled version available on the web/ftp sites). Unfortunately, the browser frequently crashes while trying to print examples that are contained in this bug. Please see bug #161967 for details of that new bug I opened.

I just re-ran the my tests with the patch for #159358 included (to fix the crash). I only get table boundaries on the first page of the tables. The second pages have no table cell lines. So I would have to say the problem is still there in 1.1beta.

Using nightly 2002112908. I loaded the testcase, printed it to a file, and looked at it with ghostview. All of the vertical lines seem to be fine, but several of the horizontal lines are unusually thin. In some cases the line is virtually invisible when viewing the printout at normal scale, but by zooming in the line can be seen. The attached image shows one of these zoomed to 800%. Brian, is this the problem you're seeing?

I think you are on to something. I just looked at an internal example (sorry, I can't post it without a lot of content removal), printed it and there are VERY faint lines when printed on a high resolution PS printer. So faint, they almost look like they are see through from the back side but they aren't. I don't have GV handy, only GS and I don't see a zoom option on it (if there is, I have a .ps file I can also view).

Okay, I think that's good enough to confirm this. I also suspect this has to do with pixel rounding, so I'm going to add this to bug 134942, the pixel roundoff tracking bug.

I tested this with a CVS build from 20031106 and I can't reproduce the effect any more. This was probably fixed by the patch for bug 80190.
