I guess you mean "will *not* change". (otherwise I'm really puzzled ;)

I waited, everything works fine now, with nice uri. Thanks a lot !


I was not sure what is who in the spool:
$ sudo ls -a /var/spool/cups/
.   00000003  00000007  c00002  c00004  c00010  c00012  c00014  c00023
..  00000005  c00001    c00003  c00008  c00011  c00013  c00022  tmp

good idea => STR #2141
(actually, it was in the refpage, but didn't appear in the toc)

I'm not sure what "BrowseAllow from @LOCAL" means. The ref page says
"The @LOCAL name will allow browse data from all local interfaces."
I guess it means that cupsd will listen at browse data on the l0 interface. Am I right ?

If so, as it is the only BrowseAllow directive in my client cupsd.conf, I don't understand how it can find the server's printer whose broadcasting arrives on eth0.

upd broadcast packets not coming from l0
