As per another message hereabouts, this is an issue that comes and goes according to what samba patches you have installed! It also seems to not happen on some systems at all. I have 4 servers running Centos 3.3 - the main one had this problem, it went away with a samba update and came back with another recent one! On the other hand, an old Gateway PIII-500 in another office has never had the problem. I don't print to the other two systems. Here's a response I got when I last posted about this in Feb: Sounds like this: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145639 which seems to be a samba bug introduced in 3.0.4 (?), still there in 3.0.9, and apparently fixed in 3.0.11 (or possibly cvs HEAD, not sure). There's a patch on that bug report that seems to fix it for most people anyway - we're about to try it on one of our RHEL3 boxes.
