Trying to install a Minolta 2300W laser printer on Ubuntu

[Bjoern Ottervik]

I get all the way through the install wizard seemingly identiying the 
(USB)printer, but when clicking apply, it hangs there for a minute and 
then exits without adding it to the list of printers.
This is what prints out in the terminal:

----
