[cups] CUPS not sending correct user name

[Helge Blischke]

Looking into the sources (cups/usersys.c) reveals that to evaluate the  
user name
to use the USER environment variable is checked first. The "User foo"  
directive
in client.conf is only taken into account if the USER environment  
variable
is not set or does not match the current UID. So you need, I think, to
undefine (or set to empty) the USER environment variable prior to  
executing
a print command.
