I am working with a client that would like to collate sales order printing. They are printing to a HP LaserJetP4015 using the HP Universal Printing PCL 5 driver. The printer has multiple paper trays with different colored paper in each tray. We are trying to print multiple Sales Orders at a time and print sales order 1 from EACH paper tray then sales order 2 from EACH paper tray. We are using the multi-part feature in Sales order printing to direct it to different paper trays, however, it is printing all the sales orders from paper tray 1 then paper tray 2, etc. The client has to collate the sales orders manually. I have tried different settings on the printer to no avail. Any suggestions would be appreciated.I
