Else, without power, the scanner can not transfer the printing data/signals to the printer. Question: Why my GDI printer does not work with the AV620C? Answer: Disable the Auto Scan function in the application, then your printer will function in normal working condition.
Question: Why some parallel port devices and software’s keypro do not work with the AV620C? Answer: The AV620C can 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.

It is suggested to use other parallel ports to connect these devices or keypro.
