Your response was on point and I thank you for it. But see my reply to yours (beginning "Well, yes. I had thought of that..." explaining that the printer is at USB002 attached directly to this laptop. And note the rest of that sub-thread including the exchange with BrowserUk.

Is there a MODE or NET USE command (perhaps in combination with other settings) that would establish redirection of LPT1 (which currently seems to be unknown on this system) to USB002.
