### Form Connection IDs

Assign a unique internal form connection ID for each different combination of tray, form, and media type a user can select. The following are examples :

The following example shows how to define four form connection IDs:

    #define CONN_ID_1      0   // auto, letter, plain
    #define CONN_ID_2      1   // auto. letter. manual
    #define CONN_ID_3      2   // manual, C10,  plain
    #define CONN_ID_4      3   // manual, A4, transparency

Note: Because the user can define uncommon combinations from the Omni Printer Property panels, every permutation need not be displayed.
