The problem is almost certainly the Java runtime - Sun/Oracle has a long-standing bug in their IPP implementation in that it doesn't support the "no-value" tag, among a long list of other things. Thus, as soon as they see something they don't support they abort the print...

One workaround it to do:

    lpadmin -p printer -o orientation-requested-default=3

on the servers; this should get pushed out to the clients automatically and allow the Java application to work...
