I have customers using both methods at rated speed. It depends what you are sending down to the printer. If you are sending line mode data with lots of fonts changes and forms invocations .... rated speed since the printers are intelligent and most of the processing occurs at the other end of the transmission. If you are sending lots of bitmap graphics .... very slow unless you are requesting multiple copies. Hope this helps. -Richard RWerezak@TORHO.Xerox.COM (416)972-7040
