Experienced Windlows user new to Knoppix. Working with Knoppix live DVD, creating persistent image on flash drive, works great. Can initially use Print Manager to setup a Canoni550 printer on a USB port, then successfully print a test page. However, when trying to print from Open Office, the Canon printer is not shown. I then get a message "cannot start CUPS server". Trying to use again set up the printer results in the same message. Is there a way to solve this when working from the live DVD. Can the CUPS server be retarted? Knoppix looks very interesting, also very frustrating. Have feeling solution to above is either simple or not possible.
