Well, that's why I'm asking the question. Perhaps the parallel port arbitrator is not installed in Windows 7 by default if the PC did not have one? If this is seems to describe some similar cirumstances, enough so that I wonder if there may be a connection. Though this does not directly apply, the knowledge base article at If I try a different device, it (as expected) reports an error that the device does not exist. Try printing another test page, and it appearsīriefly in the queue and vanishes, just like it would if the print job had succeeded.

I then install the driver for the printer, and add the printer to "LPT3" which is the parallel port device added in device manager. Under "Printers and Devices" I get 1 (Or in the case of a dual parallel port card, 2) "Microsoft aw Port" devices. Device manager gets the parallel port(s) under Ports (COM & LPT) however it also gets a "multifunction adapter" in a different section (Not sitting at the PC now, so I don't recall which.) Both devices appear to be fine and report that they are workingĢ.

I first tried USB to Parallel to connect the printer, however, this does not work, since the printer isn't smart enough to identify itself, it will not appear as a
These PCs are for use in a point of sale application, which requires a dot matrix printer. I overlooked that they did not ship with a parallel port.
