Thanks for the update, DomLyons. So, do you mind if I close the report? :) G

Printing a PDF can take very long (and I'm not shure if the print jobs really end successfully). I have tried three cases: CASE 1: I have a PDF (a converted PowerPoint presentation, about 125 slides, 10 MB). The PDF mainly consists of text, formula and vector graphics. There are a few JPGs in it, too, but they are low resolution only. As more than 120 pages is very much to print and the font size is big, too, I wanted to print 2 slides on one DIN A4 page. Okular (or kprinter?) has a function for this so I tried to use it. After about 1 hour I didn't have at least one printed page but a CPU intensive gs process running and a temporary PS file that was far bigger than 200 MB. After some more waiting I cancelled the printing job. CASE 2: I had the suspicion that gs processed each file as seperate image to fit two of them on one page. So I tried Adobe reader togive out a ps file with 2 slides on one page hoping that this application is a bit more efficient. It really is more efficient and the resulting PS file was "just" about 130 MB which I guess is not too bad if the Reader has converted some vector grafics into rasterized images (for compatibility reasons for example). I expected it should be no big problem to print out this "printer ready" PS file... So I opened in Okular and tried to print it. But after some time the printing wasn't even started and it took a closer look at the processes running: $ ps -fA | grep gs lp 3991 2481 0 19:27 ? 00:00:00 /bin/sh /usr/lib/cups/filter/pstopdf 433 dominic Physik 1_1 1 [...] /var/spool/cups/d00433-001 lp 3992 2481 0 19:27 ? 00:00:00 Brother_DCP-120C 433 dominic Physik 1_1 1 BRColorEnhancement=ON [...] lp 3993 2481 0 19:27 ? 00:00:00 /bin/sh /usr/lib/cups/filter/cpdftocps 433 dominic Physik 1_1 1 BRColor[...] lp 3994 2481 0 19:27 ? 00:00:00 /bin/csh /usr/lib/cups/filter/brlpdwrapperDCP110C 433 dominic Physik 1_1 1 [...] root 3995 2481 0 19:27 ? 00:00:00 usb://Brother/DCP-120C 433 dominic Physik 1_1 1 [...] lp 4058 3991 61 19:28 ? 00:00:07 gs -dSAFER -dCompatibilityLevel=1.3 -dAutoRotatePages=/None -dAutoFilterColorImages=false -dNOPLATFONTS -dPARANOIDSAFER -sstdout=%stderr -dColorImageFilter=/FlateEncode -dPDFSETTINGS=/printer -dDoNumCopies -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sstdout=%stderr -sOutputFile=- -dSAFER -dCompatibilityLevel=1.3 -dAutoRotatePages=/None -dAutoFilterColorImages=false -dNOPLATFONTS -dPARANOIDSAFER -sstdout=%stderr -dColorImageFilter=/FlateEncode -dPDFSETTINGS=/printer -dDoNumCopies -c .setpdfwrite -f - (Cups is process 2481) So it seems as if the printer ready PS file is converted to PDF and back to PS again by Cups and that gs is processing it in some way, too. This semed very inefficeinto me so I canceled the printing job again as it probably wouldn't be processed any time soon. CASE 3: I thought maybe Okular and Cups couldn't communicate that the file was already ready for printing. So I tried to print the file directly using "lp" - but the problem was the same. And also printing diectly from Adobe Reader had this effect (but I guess this is hardly surprising as it seems to use "lpr"). ------------------ Maybe the problem is something completely different, but that's all I could find out. The only thing I know for sure is that I have no proper solution to print such documents which I need for studying :-( But I hope that this bug can be solved. I will help as good as I can.
