Hi Everyone
Ever since Knoppix 7.0 I have been unable to install the proprietary plugin from HP that is needed for my HPLaserjetP1102W printer to work. But finally I have found the answer, at leatst for Knoppix 7.4. At least it's a way to get the plugin downloaded and installed and the printer working.This is simply to change the ENV variable LANG, from the LANG=en_US.UTF8.UTF8, which Knoppix sets it to after a USB or a HD install to the simpler value LANG=en_US.UTF8 and then the plugin will download and install perfectly using the Bash command:

hp-setup -i -a

and the way to do this is to add a line to your /etc/bash.bashrc file:

export LANG=en_US.UTF8

and reboot [before you try installing the plugin]

How this ENV variable with the odd extra .UTF8 inserted has gone apparently undetected and uncorrected for so long I don't know, but it's great to finally have a working printer with Knoppix again.
