The MacOS client sends a PDF to the Debian cups server, and the Debian CUPS server fails to rotate it correctly. This problem doesn't actually require a MacOS client to reproduce: you can reproduce the problem by printing a landscape PDF from the command line on a Debian system: the broken PDF to PostScript converter is on the Debian system. I reported this problem as #322226, and someone else reported #289893, which looks like it may be the same problem. I've been poking at this problem on and off, and the executive summary is that there are two problems. The first was introduced in 1.2.22-6, which stopped using the internal xpdf, thus causing a regression of STR#207. This problem can be fixed using the internal xpdf instead of the filter script. The pdftops from CUPS 1.4, as provided in the Debian 1.3.6-3 package, has not solved this problem in my testing. I haven't tried newer Debian packages, nor have I experimented with actually running CUPS 1.4. The second problem which affects landscape printing is probably a bug in Ghostscript (or the way that CUPS drives Ghostscript) and applies to printers using ljet4, hpijs, and other mechanisms where PostScript interpreting occurs on the print server, not the printer. The first part of the problem could be fixed in cups or in poppler-utils and xpdf-utils. If my understanding of the second problem is correct (which I'm not entirely confident of), then it needs fixing in cups or in ghostscript. For reference, my current production print server is a Sarge system running cupsys 1.1.23-10sarge1 (using the internal xpdf, as per #322226) and gs-esp 7.07.1-9sarge1. It does not exhibit either problem. -- William Aoki KD7YAF [EMAIL PROTECTED] 5-1924 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
