Question: Why some parallel port devices and software’s keypro do not work with the QMS SC-100?
Answer: The QMS SC-100 do pass-through printing all right , but the pass-through printing may not work if you connect the parallel port with devices other than printer. Therefore, if you would like to connect some parallel port devices other than printer, please do not connect them to the same parallel port that the QMS SC-100 currently uses. It is suggested to use other parallel ports to connect these devices or keypro. For instance, you can connect the QMS SC-100 to LPT1, and connect other parallel port devices to LPT2. Or you can add a data switch to avoid the problem.
