Thanks. I'd rather reinstall 1.5.4.  

As there are 2 other people in this bug list also struggling with this, (i
think they have kyocera USB printers), do we close this bug down and attribute
the problem to dodgy printer firmware on samsung and kyocera printers?  I'm
willing to continue running any tests you think need to be run in case this is
a tumbleweed specific issue.

I doubt i'll ever understand how the USB printer is identified using the
backends okay, but the actual printer control front end can't deal with it.
