Working for an international company may require setting a printer to print labels (or other types of paper) in multiple standard sizes (e.g. A4 and LETTER). This can be accomplished through SPAD in the tray configuration screen.
Because of limitations in SmartForms we have to take several steps when designing labels to allow output of multiple label sizes. All labels are initially designed in A4 format since it is longer than LETTER. In SPAD the alternate paper size, in our case LETTER, should be assigned to the first paper tray.
If the transaction SPAD is not available, due to security restrictions, then the tray assignments can be viewed using SE16. The table TSP03T shows the output device's tray assignments.
