while posting Packing slip -- Cannot render the report to the screen when running in non-client mode

Cannot render the report to the screen when running in non-client mode (for example, in batch or in IL). Change the print destination to a location other than the screen. For example, a printer, file, or email.

here is my logic please update me thanks in advance
