there is something not standard about that stream.I've tried it before w/ RPCS, PCL/Universal Print Driver, PostScript and all were complete failures. I put in another box w/ emulated postscript and had some better results but still the output wasn't right and the trays wouldn't switch.. had an SE d/l print streams and send them up the line, on and on.. The thing that is really frustrating about it is to put yourself in the customer's shoes.. they are being pushed around pretty hard right now by auto mfg's and paying thru the nose already to either R&R or ADP and now R&R is further tightening the noose
