That should never happen; can you post a link to your error_log file  
with the LogLevel set to debug2?

A single failed job will not stop printing on other queues. The  
default error policy for queues is "stop-printer".  You can use "retry- 
job" to get the job to retry or "abort-job" to cancel it.

lpadmin -p printer -o printer-error-policy=foo

Not that I know of, but iptables is Linux-specific...

CUPS uses port 631 TCP + UDP.  LPD uses port 515.  AppSocket is  
typically port 9100.
