Re: How long until a deleted printer actually vanishes?
Hi,
the iPad issue seems to have solved itself by just waiting for a while.
I suspect the iDevice does some caching. I am therefore only replying to
this mail for completeness of archives.

Yes, they're visible.

No, they aren't. The printers, parada, fan, and the iPad are on four
separate VLANs, with my Debian router/firewall, barrida[1], being the
hub. This has the advantage of being able to see the complete traffic of
all machines by tcpdumping on barrida. Both printers are on the same
VLANs.
barrida is also running avahi-daemon in reflector mode:
[2/3341]mh@barrida:~ $ grep -vE '^(#.*|)$' /etc/avahi/avahi-daemon.conf
[server]
use-ipv4=yes
use-ipv6=yes
ratelimit-interval-usec=1000000
ratelimit-burst=1000
[wide-area]
enable-wide-area=yes
[publish]
[reflector]
enable-reflector=yes
[rlimits]
rlimit-core=0
rlimit-data=8388608
rlimit-fsize=0
rlimit-nofile=768
rlimit-stack=8388608
rlimit-nproc=3
which seems to do a good-enough job.
Since the iPad now sees both printers, this case can be closed as well
;-)
Greetings
Marc
