I'm trying to use an old parallel-port based printer with a USB-to-parallel port adapter on Windows 7. When I plug it into the USB port on the computer it's listed as an unrecognized device. I know that these cables typically use the "USB Printing Support" driver with makes USB ports show up as printer ports in the printer dialog. Is there a way to manually add USB Printing Support to Windows 7, since it isn't being added automatically?
You can add the printer manually via:
If the printer model is not available, you will need to manually supply the driver.
The USB-to-parallel port adapter should have come with a driver. If the driver is not installed, then the device will indeed show up as unrecognized. If you don't have such a driver, please let me know the manufacturer and model of the adapter and I'll try to find one. I'll also need to know whether you're running Windows 32-bits or 64-bits.
I am not sure in this case, but USBDView may show what vendor ID the adapter is, might be worth a try.
