Dear Amol
this is a long story. I will try to summerize it only on high level (and frankly speaking it is long ago there if have had a "similar" topic on the desk):
Automatic SDS shipment: based on your customizing set up here the "print" is routed to a printer; in doing so a WWI server is used before that to do the "final report"; you can not discuss your topic without discussing both topics.
Now there a number of questions which need to be answered:
1.) which printer is used to do the joNB? is it always the same one (normally not)
2.) which printer settings are there in SAP (if i remember correct it is not an easy job got "prepare" the printer in connection with SAP
3.) ... and a lot of further issues
Second: the whole topic depends on set up of WWI server farm etc.. Any WWi server need to have the same set up (and there is an exit which could be used to something special; but I do not know if you have used it)
We need to differentiate a little bit your second topic (and I am sorry it is long ago there I need to dig such "deep").
If you use CG54 and "print" the final report via SAP (as MAN_CALL) I am not sure if you local SAP gui (client) set up does have some printer effects; but normally it should not happen, as you use the same SAP printer as in the SDS distribution
Conclusion: to get the topic solved you will need to invest a lot of time (be aware of the fact that the effect can be different on dev, qual, prod etc.).
But I "struggle" a little bit (it is to long ago) and may be same local client set up has effect on printing;
But may be my hints help you to start the analysis and excluding "reasons".
