If your small business is typical, you want to get the longest lifespan possible from your tech investment, and therefore you may have an older dot-matrix or laser printer with a parallel port that you want to use with a modern computer. Since the early 2000s, USB has gradually become the standard for printer connections and therefore many modern PCs do not have parallel ports. You must use a USB-to-parallel adapter cable for older printers. Usually, installing the adapter and using it is relatively straightforward and hassle free. If you experience connection problems with the adapter, however, you can usually troubleshoot and correct the problem yourself.
Check for Loose Connections
2.Disconnect the parallel end of the cable from the printer. Push the parallel end of the cable adapter onto the parallel port of the printer. Push firmly on the cable adapter end until the connection with the port is tight and secure. Ensure that the clips for the parallel port and cable are in the locked positions.
3.Unplug the USB end of the cable from the USB port on the computer, and then reinsert it. Push firmly, but gently, on the USB adapter until fully seated.
4.Power on the printer first, and then the computer. Allow the computer to boot into Windows, and then attempt to print a document from Microsoft Word or another application.

Click Start and then “Computer.” In the Windows Explorer window that appears, click the “System Properties” link on the toolbar.
2.Click the “Device Manager” link under the Control Panel Home label in the System window. A new Device Manager window appears on screen.
3.Double-click the arrow next to the “Ports (COM & LPT) header in the Device Manager list. The list expands and displays the ports installed on the computer. Select the port value labeled “USB to Parallel,” “Virtual Parallel” or “USBPAR.”
4.Right-click the selected port device name, and then click “Uninstall” on the popup list. Windows deletes the virtual parallel-port adapter from the system. Close the Device Manager and System windows.
5.Restart the computer and wait for it to boot into Windows. After the computer reboots, Windows redetects the USB-to-parallel port adapter and reinstalls its driver. If the old configuration conflicted with another device or used resources not available, reinstalling the device in this manner should force Windows to choose a new IRQ and/or other applicable resources.
6.Attempt to use the printer connected to the USB-to-parallel port adapter as you normally would.
Reinstalling the Driver
1.Click 'Start | Computer | System Properties | Device Manager.' After the Device Manager window appears on the screen, click “Ports” and then select the device name of the USB-to-parallel adapter. Right-click the device name of the USB-to-parallel adapter, and then click “Properties.”
2.Click the “Driver” tab in the Properties window, and then click the “Uninstall” button. When the Confirm Device Uninstall window appears, click the “OK” button. Windows uninstalls the driver and deletes the device from the Device Manager list.
3.Insert the driver installation disc for the USB-to-parallel adapter into the optical drive the computer. Wait a few seconds for the installation or setup wizard to appear on the screen, and then click the “Install” or “Setup” button. Follow the remaining prompts to reinstall the driver in Windows. If prompted to do so, restart the computer. Attempt to print to the printer connected to the USB to parallel adapter after reinstalling the driver.

Most newer computers do not come with a parallel port to use for older types of printers. You must use a cable that can convert a parallel connection to a USB port on laptop or desktop computer. If the printer is not working correctly when the cable is attached, troubleshoot to find the cause of the problem.
Installation
Make sure the USB to parallel cable is properly connected to the printer and the computer. Depending on the type of cable used, there may not be a viable way to lock the parallel connector to the printer. If the cable does not have a solid connection, the printer will not be detected by the computer. Also make sure the printer has been turned on in order for the computer to recognize the connection from the USB port. If the printer is not being recognized, there may be a software issue.
Drivers
When using a USB to parallel connector cable for an older printer, the computer must have new drivers installed. Insert the CD that came with the USB to parallel printer cable to install the needed drivers on the system. When a USB to parallel cable is connected, the computer will use the USB port to send information to the printer. This will require installing new software and then setting up a new printer using a USB connection. Once the new drivers have been installed, plug the cable into the USB port to have the system automatically configure the printer port.
Conflicts
When you install the USB to parallel cable, the computer may not recognize the printer, or it may not print correctly. This can be caused by currently installed printer drivers that are not working correctly with the new USB to parallel cable. You may need to use a Windows generic driver instead of the driver that was supplied with the printer. Use the 'Add a Printer' option from the 'Printers and Faxes' option in the Control Panel to add a generic Windows driver. You can also check to see whether the manufacturer of the printer has an updated USB driver available to install.
