I'm running Red Hat 7.3. The KDE KGostView pdf viewer won't print pdf files. It gives the message: "The file format application/x-zerosize is not directly supported by the current system." KGostView asks: "KDE convert this file to application/postscript ?" So I agree, but it fails and says: "no appropriate filter" My printer is an Epson 640 which I loath but can't afford to replace. RH 7.3 with KDE prints text OK. I've even printed a couple of HTML pages using Konqueror.. Anyone know how I can get KGostView to print PDF? The problem is not the printer. My system is multi-boot so I booted into Slackware 7.1 Gnome and used the Gnome Ghostview 0.95 to print the PDF file, no problem. But I don't really like Gnome and KGostView should do the job in Red Hat 7.3. What have I failed to do in Red Hat 7.3 ?
