Comment 66 for bug 277404

Roger, note that Gentoo and Ubuntu have completely different filter chains, Gentoo uses probably the original PostScript-centric model of upstream CUPS and Ubuntu (and Debian) use a PDF-centric model. So problems you find in Gentoo do not necessarily occur in Ubuntu and me as maintainer of the Ubuntu printing stack cannot help you much in solving Gentoo problems. So you should better file a bug on Gentoo's bug tracker. You can naturally reference to this Ubuntu report and the Poppler upstream report.
