Verify that:
1. The printer is turned on and is online.
2. The printer signal cable is connected to the correct serial or parallel port
on the server.

Note:
3. You have assigned the printer port correctly in your operating system or
application program.
4. You have assigned the printer port correctly using the
Configuration/Setup Utility program.
If the items above are correct and the printer still does not work, run the tests
described in the documentation that comes with your printer. If the tests
show that the printer is OK, call for service.
Verify that:
1. Each port is assigned a unique address by the Configuration/Setup
Utility program and none of the serial ports are disabled.

connector, but it is used only by the integrated Netfinity
Advanced System Management Processor, and is not available
for use by the operating system. This port does not appear in the
Configuration/Setup Utility program menus; it can be
configured using Netfinity Manager.
2. The serial-port adapter, if you installed one, is seated properly.
If the problem still exists, call for service.
