[cups.general] Problems registering printers with Avahi

[Mario Aeby]

Dear list

cups 1.3.8-1+lenny7
avahi-daemon 0.6.23-3lenny1

I have troubles registering some of our cups printers with the local avahi daemon:

According to the source code, error -65537 means:

- --
kDNSServiceErr_Unknown             = -65537,

When looking at it with debug2-level:

As you can see, two of the five printers can be registered (NRGMPC4500 and NRGMPC4500PS) because it seems their entry only gets "updated". So it seems to have worked a while ago.

The two printers show up in bonjour, the others are missing.

Looking at the avahi log I see:

The main problem seems to be "Responding error 'Invalid service name' (-10)"

Does anyone have a clue what's causing this problem and how to get rid of it?

Best regards
Mario
