Well, Ubuntu is known as a good choice for newbies. The problem is that noone installs Linpus on his computer, Linpus is only available preinstalled on computers (instead of Windows) because it is cheaper than Windows.
I don't know which software Linpus is running for printing, most distributions nowadays use cups. If cups is installed and running, you may open a browser (e.g. firefox) and open the adress
which is the webinterface of cups where you can configure your printer. It is necessary to configure the users who are permitted to print.
