Hi, Seems I am having more info about the offending images. If I try to run jpeg2ps on one of the problematic jpeg images I get $ jpeg2ps kk-000.jpg > kk.eps Warning: JPEG file uses compression method C2 - proceeding anyway. PostScript output does not work on all PS interpreters! If I rebuild the pdf file after processing the jpg with imagemagick's convert $ convert kk-000.jpg kk-001.jpg problem seems to go away. So, this is apparently related to jpeg compression method. > I noticed that for cups 1.3 or higher a pre-processing filter can be used. > If pstopdf cups filter is available, adding following lines to ppd file > seems to make things work here, pstopdf filter is no longer available, so this no longer works. But at least I know now why it was useful. Regards, -- Agustin
