default printer settings in SAP

Hi all,

In Vl03n, i am going to outbound delivery -> issue delivery output . Then i am selecting one output type( let say zp01).

Then i am giving print for this delivery order.

I am changing the printer name in the print option but the print

is not going to the said printer but it's going to a default printer always.

so, in SAP, how & where they configured default printer?

points will be awarded.

Thanks
