Enabling and disabling protocols

A protocol is a method by which a host system sends print data to the printer. An adapter supports one or more protocols. After an adapter is physically installed, it must be logically installed before it can be used. A LAN adapter, such as the on-board Ethernet adapter, must be logically installed but channel adapters are automatically marked as logically installed.

Once an Ethernet adapter is installed and enabled, the protocols for the adapter may be installed and enabled. Use the Network-Attachment panel (Printer Definition -> Network -> Attachements) to install, enable, disable, and uninstall adapters and protocols.

After a protocol is installed, it may be enabled or disabled. When a protocol is enabled, a host system may send print data to the printer using that protocol. You can enable and disable protocols using the Manage Protocols panel (Frequent Tasks -> Manage Protocols).

The installed state of each adapter is global. This means that an adapter that is installed on a Duplex configuration is also installed for the Dual Simplex configuration. On the other hand, the installed and enabled state of protocols is maintained at the printer level. This means that a protocol that is installed and enabled on a Duplex configuration may be uninstalled on Printer 1 of a Dual Simplex configuration and installed but disabled on Printer 2. The installed and enabled state of protocols is not changed by a system restart or a shutdown/startup sequence.

After a protocol is enabled on a printer, commands may be entered on a host system that communicates with that printer.
