Piranha cluster only use one node when printing from an AS400 (clustered cups)

I got a piranha cluster for my printing servers as shown:

2 chief servers running RH5
3 nodes running rh 4u4 with cups

When I print from another linux computer using lpr -Pcluster file.txt the printjob go to each of the three nodes in a round robin fashion (as expected), but if I do the same from an AS400, all documents go to the same node (which makes the cluster pretty useless).

Any ideas on why the printjobs dont get distributed evenly between all three nodes when printing from an AS400 but does so from a linux computer when printing 3 times?

I'll ask the million dollar question....what arguments are you sending when you issue the lpr command from the AS400?

Just in case someone else is looking for a similar issue.
Reason for that. Is that round robin works for multiple clients. Each time a client request resolution it gets redirected to a different server in the round robin list. If you are balancing from a single Server to a round robin, you will usually always hit the same cluster member.
