Is the printer managed by a cups server to which your client then relates to, 
or your configure this printer directly on your local machine (which probably 
runs a cups server).

What happens when you try to release one of these held jobs?

What is then marked as, before turning on the printer, if not "Held"?

From the Printer Properties in KDE Printer Manager?

The same as in "prints correctly" or as in "job gets held"?

Most assuredly. But your printer gets data, thus we know at least 
communication between your OS and the printer is correct.

In the list of the KDE addprinterwizard?

What is this "Normal"? The KDE addprinterwizard, or some Ubuntu tool?

This might be a problem induced by a particularity in the configuration of 
CUPS in your OS, combined with some path hardwiring that KDEPrint is guilty 
of.

You might want to deactivate certificate authorization in /etc/cups/cupsd.conf 
and use basic authentication instead.

A bit more information on this in:
http://bugs.kde.org/show_bug.cgi?id=129137

it's related to Fedora, but it might have something for you too.

You might want to add the line

Listen localhost:631

before the line
Listen /var/run/cups/cups.sock

in /etc/cups/cupsd.conf
