Comment:
Thank you RoX!

If I make the suggested change of /dev/usblp0 from scanner to root, my
Epson CX3200 scanner/printer is detected by the gui Add Printer system.
It prints a test page, and is still recognised by XSane as a working
scanner.

The goodness doesn't survive a reboot of course;  although the printer
is still listed as installed it is now back in the scanner group and so
won't print until the manual change is made again.

My naive take on this is that the problem is the multi-function device
identifying as only one of its functions and therefore ending up in a
restrictive group.  Thus gnome-cups-manager and gutenprint drivers are
innocent.  The problem perhaps lies in udev/hal magic that I do not
understand...

Surely there should be a witty t-shirt for *nix people with a slogan on
the lines of "It's always a file permissions/groups problem...".  But
witty of course, rather than just descriptive ;)
