To set your kitchen printer to use SHARED settings, go to MENU > SETTING > HARDWARE > KITCHEN > BASIC then select SHARED as the TARGET.
If you are sharing settings with more than one kitchen printer, you will have to check the USE box under the KITCHEN # tab for the number of kitchen printers that will be used.
For example,if you are going to share settings for two kitchen printers, you would need to check the USE box for Kitchen #1 and Kitchen #2.
