Printer software installation

Incorrect or incomplete software installation can lead to USB problems. Take note of the following, and perform the recommended checks to ensure proper installation.

Checking printer software installation for Windows XP and 2000

When using Windows XP or 2000, you must follow the steps in the Setup Sheet packed with this product to install the printer software. Otherwise, Microsoft's Universal driver may be installed instead. To check if the Universal driver has been installed follow the steps below.

Open the Printers folder and right-click the icon for this product.

Click Printing Preference on the shortcut menu that appears, then right-click anyware in the driver.

If About is displayed in the shortcut menu that appears, click it. If a message box with the words "Unidrv Printer Driver" appears, you must reinstall the printer software as described in the Setup Sheet. If About is not displayed, the printer software has been installed correctly.

Note:
If the Digital Signature Not Found (Windows 2000) or Software Installation dialog box (Windows XP) appears during the installation process, click Yes (Windows 2000) or Continue Anyway (Windows XP). If you click No (Windows 2000) or STOP Installation (Windows XP), you will have to install the printer software again.

Checking printer software for Windows Me and 98

If you canceled the plug-and-play driver installation in Windows Me or 98 before the procedure was complete, the USB printer device driver or the printer software may be incorrectly installed. Follow the directions below to ensure that the driver and printer software are installed correctly.
