Insert the disk or any media where the printer software is stored to the corresponding drive.Do you see a "readme.txt" or "readme.doc" file? Open that and read the contents of the file. Once the executable file is run, the installation process will automatically begin. Get the box which came with your printer software CD and take note of the registration code or key. You might need to enter this data later during the installation process or when you need to reinstall the software all over again!
