hmm b2k and c3k are very brother system in term of architecture and 
components? May I ask you the amount of ram stand in your c3k? (on my 
b2k only 256k).

Sorry, via network (hp lazerjet 4mv)

Certainly :( [but where, the rest ftp, rsync, nfs-client, gtk-app, ... 
work fine and no special messages neither into kernel, messages or 
syslog?]. Well don't care now, it is just a beat anoying to printout my
