Poppler is generally used for processing PDFs where > Ghostscript is primarily used for rendering Postscript (and sometimes > PDF) to raster formats. PDF is basically just based on a slight modification of Postscript, so there is a big overlap between the two. A PDF file is basically a Postscript file which builds an object tree which represents the document and contains content streams (which are Postscript) to render the page. So I don't agree that it isn't a waste. Remains the problem that if you want to print postscript, you need to install Ghostscript with the cups option, but the resulting package conflicts with cups-filters. That isn't very practical. On the other hand there could easily be a filter in cups-filters that uses (plain) ghostscript to convert PS to PDF and continue with that. But that also isn't there. (And I'm not saying that pkgsrc should add something like that if it is messed up by upstream; but there definitely seems a lack of coordination somewhere.) -Olaf. -- ___ Olaf 'Rhialto' Seibert -- Wayland: Those who don't understand X \X/ rhialto/at/falu.nl -- are condemned to reinvent it.
