Version: (using KDE KDE 3.5.5) Installed from: Debian stable Packages Reported in Debian BTS at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=399690 When printing a HTML document (from konqueror f.ex.), one can choose the "Print header" option in the "HTML Settings" tab (it's on by default btw.). If this is enabled, then kprint will *overwrite* the top of the page with the header of the page. This is less of a problem when printing single pages - you can see the result of printing [1] into a PDF and displaying it in xpdf in the first attached screenshot - notice that the logo is cut off at the top by the page header. But it becomes a bigger problem if there's little space on the sheet and kdeprint pushes the text up towards the border of the sheet as seen in the second screen shot where text is actually lost and the printed document becomes unusable. This can be seen in the second attached screenshot. It's the same document but printed through the Pamphlet filter that puts multiple pages on one sheet. Whether output goes to PDF or directly to the printer doesn't matter here. (see Debian bug report for screenshots)
Whatever data konqueror generates for printing, this is what kdeprint takes and prints. The "HTML settings" tab is introduced in kdeprint's dialog by konqueror/khtml. It is the application that handles this information. So, this bug is reassigned to konqueror.
Olivier, if you enable the "Print header" function, you need to make the top margins big enough at the same time in order to accommodate for header. (Custom margins may be set for khtml and text (Konqueror + Kate) printing on the separate tab named "Margins"). I'll close that bug report for now. That said, I want to hint at two other possible problems, which I had no time to verify with 3.5.7 yet, but which I recently saw shortly on a customer system running KDE 3.5.3: --> the margins somehow do not work correctly. He had to choose s.th. like 4cm for the top margin in order to get 2cm on paper. Looked a bit like there was an A4 vs. Letter size mismatch. --> also, using the pamphlet pre-filter did not fully work. The PostScript pre- view looked fine + perfect, but on the paper printout it appeared like it was scaled for Letter... I'd be happy if you (or someone else) could check these points more thoroughly against KDE 3.5.7, and submit two separate bug reports (or 1, if it is the same problem), with the proper description and headline. For testing both features, correct margins and pamphlet pre-filter, (as well as a combination of them), please use the "Print to PDF" printer. The specific thing you reported here ("print header" overwrites page content) can be avoided by setting the margin large enough. Not sure if margins and page sizes work exactly as they should.
Let me add one more thing: in the past, the "print header" feature printed the header on a fixed distance from the top edge of the sheet (regardless the margin setting), and the rest of the page did honor the margin setting. I do not know if that behaviour has been changed in recent KDE versions. If it did, you should re-open this bug, because then my advice is no longer valid.
