That's a really interesting speculation that makes a certain amount of sense since there is a strong printing component to the EPS and PDF formats. However, I am not sure this would be an issue for the downloadable Qt SDK. For that case, they probably provide their own CUP libraries since the Linux ones come in all sorts of versions/configurations which would be hard for trolltech to anticipate. Also, this may not be an issue for Debian. When I first tried qt, I just used the Qt-4.4.3 Debian packages, and as best I can remember I tried pdfqt a couple of times without any noticeable pdfqt speed issues. OTOH, I may not be remembering right, and in any case most of my pdfqt testing has been after I moved to the downloadable Qt4 SDK you can get from trolltech. Did you use a Ubuntu package for Qt-4.5.0 or the downloadable SDK (which is now Qt-4.5.1, but it was 4.5.0 not that long ago). If you haven't yet tried that downloadable SDK, I suggest you do so to see if this (Qt4?/cups?) problem persists. Alan __________________________ Alan W.
