2. Click the link that represents your computer's operating system.

3. Scroll down the page, and click the "Download" action, below the "Driver - Universal Print Driver" table. Opt to save the driver, as the download file has the setup application that is needed to install it.
4. Double-click the setup application's icon from its new file location on your hard drive. The HP installation application will open automatically.
5. Click "Next" to proceed to the first installation steps.
6.Select all of the HP recommended installation options, and click "Next" to begin copying the driver's files and components to the computer.
7. When the HP installation wizard asks, plug the HP LaserJet 1320 USB sync cable to the USB port, located on the back of the printer hardware. Connect the other end of the cable to an open USB port on your computer.

8. Click "Finish" to complete and conclude the HP LaserJet 1320 series driver installation process.
Hope it helps.

Thank you for using FixYa.

Is there a typical application you are using? I noticed that file size (especially in adobe) can be an issue. If you go to printer settings (start / settings / printers / right click on the 1320 and select properties) choose device settings and the very bottom item is printer memory. I would increase this to like 80mb.... hope this helps

One of the things you could [if you havent already tried it] is turn off the printer and disconnect the AC Power cable. the press and hold down the power button for, about 30 seconds then release it. After that reconnect the power cord and turn on the printer. this process should have reset it

hi..
what about the ink levels...open the backdoor of the machine and check for any obstacle....disconnect all the cables..press and hold down the power button for 30 sec..reconnect all cables..try again...try connecting the machine directly to the walljack.

Try changing to a new USB cable
