I am having an issue with OS 9.2.2. Of the 3 people using Macs 2 of them are unable to print to the same printer at the same time. The were fine before we moved them onto a switch. The one only difference between the first two and the one that is unaffected is the version of open transport: 2.7.9 vs. 2.8.3.
When one Mac prints the other can't see that printer in the chooser window.
Any ideas appreciated, solutions awarded with points!
