3284 Model 3 printer operation

When attached to a 3275 terminal, IMS supports the 3284-3 printer as a component of the 3275 terminal. IMS considers the display portion of the terminal to be component 1 (COMPT 1) and the printer portion to be component 2 (COMPT 2).

As with any component-type terminal, IMS sends messages to the two components on a rotating basis.

If IMS cannot send messages to the printer component, it sends messages continuously to the display component, as if no printer component existed. The operator must intervene to allow printer output.

If IMS cannot send messages to the display component, it sends messages to the printer as if the display component did not exist. As long as IMS can send messages to the printer component, no operator intervention is required.

Any situation (such as a stopped LTERM or non-operational printer) that prevents sending messages to the LTERM or LTERMs assigned to a particular component causes IMS to stop sending messages to that component.

To suspend messages to either the printer or the display component, use the /RCOMPT command with the NOTRDY keyword. This command sets the component that you specify as non-operational (not ready) if the 3270 is attached using VTAM®.
