How do I install my USB or parallel port printer on Windows XP?

When using Windows XP to install one of the listed printers using the software included on the installation CD, it may be found that it is not possible to install the printer when it is connected to a local port, e.g. parallel or USB, as the "Local printer" option is disabled. This functionality is intentional and was introduced due to problems encountered in installing unsigned drivers on Windows XP. If an unsigned driver is installed before the printer is connected, Windows XP searches for other potential drivers, some of which may be unsuitable. Rather than risk potential problems caused by installing the wrong driver, this functionality has been disabled and it is instead recommended that users install a locally connected printer by using the "Plug and Play" functionality of Windows XP. This article describes the recommended alternative method of installation for printers connected by USB or a parallel port.
