How to process an output message after pick and pack in LM46?

Question

Hi,
I've implemented the User Exit to print the HU using LM18, it's working great but no output message is processed (and indeed, the sticker is printed on my own printer instead of the one defined in my Z custom output message).
I used LM46 to pick and pack the HU, am i missing a step?
In other words, how to process my custom output message after the pick and pack?
Is there some code I must add in the LM18 User Exit?

You know, in a user exit or a BADi you can access any variable of the program you want.
Just find what which program calls the Exit User, put a break-point in it, and find the variable you need to access.
Then add this kind code in your Exit :
DATA: l_var TYPE ....
FIELD-SYMBOLS: <fs_var>    TYPE ANY.
ASSIGN ('(PGMNAME)variable') TO <fs_var>.
IF sy-subrc = 0.
  l_var = <fs_var>.
ENDIF.
Same thing for a table :
DATA: lt_var TYPE TABLE OF....
FIELD-SYMBOLS: <fs_var>    TYPE ANY.
ASSIGN ('(PGMNAME)table[]') TO <fs_var>.
IF sy-subrc = 0.
  lt_var[] = <fs_var>.
LOOP AT lt_var ASSIGNING ...
ENDLOOP.
ENDIF.
