Comment 14 for bug 1133794

@Finog

Also:
sudo /etc/init.d/cups start
does the same job.

HOWEVER, when you reboot your machine, it will be disable again:

Run:
status cups

and it will give you: cups stop/waiting

I think (not sure): cupsd.conf (/etc/cups/cupsd.conf) must be configured to auto enable CUPS upon starting the system up so no need to keep manually running

sudo start cups
or
sudo /etc/init.d/cups start

I failed to learn how to edit that.

There is a Question on AskUbuntu I have read it but I'm too tired and sleepy right now to understand everything (it is 4am my time).

Thanks!

We are not talking about the LiveCD or LiveUSB, we are talking about Lubuntu 13.04 after installation :)
You can refer to my comment #7 - I have tested it on 4 different installations for Lubuntu 13.04 on two different machines, one has only one installation and the other machine has 3 installations, each on different partition and each installation was made by different approach (upgrade, alternate and desktop).
