There are 50+ computers in my building connected to a server running OS9.2. The server software is appleshare 6.3. The computers are running OS 9.1 and OS 9.2. Epson printers (C80 and 980N) are connected to the network by ethernet cable and print servers. Sometimes users select their printers and the print job does not occur or a print message appears on another workstation. No matter how many times I select the printer, it does not print. I find this odd when the printer was working five minutes earlier. What is happening?
