Printers can be defined or modified once the region has been started, using the 
               		Enterprise Server for .NET Administration UI's 
               		Printers view, or from the command-line using the 
               		seeout or 
               		casoututilities. Normally, printers would be defined in the region startup file to ensure that they are immediately available to
               print job outputs once the region starts. However, there may be a need to modify the properties of existing printers, or start
               new ones after a region has been started, due to a change in workload, for example. This procedure demonstrates how to define
               printers in a running JES region, from the 
               		Enterprise Server for .NET Administration UI's 
               		Printers view: 
               	 
            
 
            	 
             
               		 
               		  
               - Select the running JES region from the Tree pane under 
                  			 , and click 
                  			 Printers in the 
                  			 Actions pane. 
                  		  
                  The 
                     			 Printers view is displayed in the 
                     			 Results pane, showing each of the printers currently configured. 
                     		  
                   
- A printer may be enabled or disabled by selecting it in the list and checking 
                  			 Enabled. If the printer being disabled is currently being spooled to, the print operation is allowed to complete, but no further
                  spooling to it will be allowed until it is enabled again. 
                  		  
               
- To create a new printer, click the 
                  			 Add Printer icon in the toolbar. 
                  		  
                  The 
                     			 Add JES Printer dialog is displayed. 
                     		  
                   
- Enter the name of the new printer, the job classes associated with the printer and a description of the printer in the 
                  			 Printer name, 
                  			 Classes and 
                  			 Description entry fields respectively. The browse button at the end of the 
                  			 Printer name entry field can be used to browse and select an installed printer as an alternative to you entering the name by hand (
                  			 
                  		  
                  The 
                     			 Advanced tab is displayed. 
                     		  
                   
- By selecting 
                  			 SEP node affinity, you can specify the URI of a machine, or a network load balanced set of machines, on which outputs associated with this
                  printer are to be printed. Enter the name of the machine/ node in the 
                  			 Host entry field. The full URI is displayed in the 
                  			 URI entry field. The full URI only needs to be entered if a non-standard URI is being used in the scale-out. 
                  		  
                  Reasons to restrict the printing of outputs to a specific machine, or set of machines, include: 
                     			 
                       
                        				
                        - The associated physical printer may not be available to all machines 
                           				
                        
- The outputs need to be printed from machines in specific geographic areas 
                           				
                        
 
Click 
                     			 OK to dismiss the dialog and create the printer. The newly created printer now appears in the list of printers in the Results
                     pane. See 
                     			 6 in the diagram below : 
                     			  
                     		  
                   
Note that any changes made in this view will be lost at the next cold-start of the region unless the corresponding changes
               are made to the printer configuration in the region startup file. However, changes made in this view will be retained across
               subsequent warm-starts of the region.
