Overlay overlayMode

Model : CT1721C, CT1820, CUBLOC + GHB3224C

This command determines the drawing logic mode between layer 1 and layer 2. Usually, layer 1 is for text and layer 2 is for graphics. By using this command, the user can specify the overlay mode when layer 1 and layer 2 are displaying on the same position.

The default is XOR, which will invert when layer 1 and layer 2 print to the same positions. OR will allow graphics on both layers to overlap. AND will display graphics only where they overlap.
