I like your Knoppix 5.1.1 best. It works on most of my machines. Knoppix 5.3.1 is more difficult and does not work on as many machines as Knoppix 5.1.1.
My question: Knoppix 5.1.1 does not have all the printer drivers installed I need. Is it difficult to add printer drivers to Knoppix 5.1.1 (e.g., for the HP Deskjet F2180)?
You need a current hplip package to fully support this printer (also to use the integrated scanner with XSane; it's an all-in-one printer/scanner device, isn't it?).
The commands to install hplip are
sudo apt-get update sudo apt-get install hplip
but if you notice that this pulls in too many packages as dependencies – for example if your cups-based printing system is too old – you might try an older version
sudo apt-get install -t stable hplip
to get your printer up and running.
