USB-C naar parallele printerkabel

When you troubleshoot issues with a parallel device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

• Parallel cables

• Parallel ports

• Parallel devices

To test your setup components, try the following:

• Use the parallel cable, parallel port, and parallel device in another setup to see if the problem is with the components or the setup.

• Use a different parallel cable, parallel port, and parallel device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

• Test each cable individually.

• Use short cables when you are testing.

When you test the parallel ports and parallel device, it is recommended that you do the following:

• Press the Windows key + R, type devmgmt.msc, and press Enter. Check to see if the parallel ports and parallel device is listed under Ports (COM & LPT).

• Make sure that the LPT port number is the correct number for the parallel device and that the software being used to connect the computer to the parallel device uses the correct LPT port number. 

• If you do not see the LPT port number in Device Manager please see this FAQ for PCI/PCIe expansion cards: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows
  or this FAQ for USB devices: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows

• If the device is listed with an error, follow the instructions on the website to reinstall the drivers.

Note: Some parallel devices only work if the LPT port number is between a certain range, usually LPT1 or LPT2.

This issue was the result of a Windows update that has recently been fixed in the KB3140743 update. If you are still experiencing this issue, download the latest Windows update.

This USB parallel device is only intended to be used with printers. Your operating system will register this device as a USB Printer Support device and not as an additional LPT port. If you need a USB parallel device to handle parallel devices in addition to printers, consider the ICUSB2321284.
