Even though the printer is displayed as an IEEE1284.4 device in the Device Manager of the Windows operating system, it may still not be able to print. This happens if the device drivers have not been installed correctly. The device drivers of the printer can be installed by choosing the update driver option from the Device Manager. Operating systems such as Windows XP or Windows have an extensive library for device drivers for various hardware such as Flash drives, printers etc. When choosing the driver, the support of USB printer IEEE1284 must be chosen to install the correct device drivers for the printer.
