I recently upgraded all my files. My HP 1200 Business Jet with a duplexer that had been working fine up till then suddenly produced some rather strange copy if it worked at all. It was working with a Linksys WPS54G print server. After trying every possible setup combination using either the online setup (
http://localhost:631/admin) or the KDE setup I found a problem, the print server apparently uses port 9100. After fiddling with this problem including adding listen to the server config file I was getting nowhere. I then tried to use a straight USB connection. Again cups 1.4.2 refused to print in duplex from a file although a test page would print both sides from the online setup On checking my laptop that has not been upgraded and runs cups 1.1.x the usb setup works OK after I use the online setup to enable the duplexer. One obvious difference is the driver. The laptop uses Foomatic/hpijs that is not available in the driver list in cups 1.4.2
My question then is can I simply copy some of the old files from my laptop setup to the desktop and if so which ones and what is their location. Another option is simply reinstalling my original system files. I'm concerned that this could wipe out much of my data even though it is (in theory) backed up to a portable disc.
I need help. While I've used one Linux distro or another for several years I'm still unsure of the directory structure and where things should be.
