Hp Printer Driver Unavailable or Not Found

To fix the problem, try the steps below the queue. At each step, check whether the problem has been resolved; If not, follow the next step.

Install the latest scanner drivers, then restart the system:

1. If a TWAIN file is missing or damaged, Acrobat returns an error message when you attempt to scan using the TWAIN interface. Reinstalling the scanner driver 
2. To reinstall the driver, delete all files and folders that start with Twine in the Windows or Windows folder (for example, “Twain_32.dll”). Then restart Windows and then install the latest scanner driver according to the manufacturer’s instructions or steps mentioned here.

Check if the device is physically connected:

1. Check the cables for the USB cable, LAN cable, etc. used to connect the scanner. Disconnect and reassemble the cables to make sure the connections are correct.
2. Make sure the scanner is enabled and no error message is displayed on its display (if any). If there is any error or if the scanner is stuck in any process, restart the scanner.
3. Windows can install both TWAIN and WIA drivers. Similarly, the Macintosh may contain both TWAIN and ICA drivers. Try scanning any other scanner driver replacement (ICA, WIA or TWAIN) if one does not work.
4. On Windows: Select any TWAIN and WIA drivers on the scanner selection screen in Acrobat as shown in the screenshot below.

On Mac: Select any TWAIN and ICA drivers on the Scanner selection screen in Acrobat as shown in the screenshot below.

 Check if the scanner works with any other application:

1. Windows and Macintosh have some built-in and third-party applications, so you can try using the scanner:
2. For Windows, there is a software called TWACKER,  scanner driver test application. It is available for free. Download and install your scanner to see if it works.
3. As for OS X, there is a pre-installed image capture application that can be used to check if the scanner is working or not.
4. Alternatively, if any other application that uses the scan function is installed, you can use it to test whether the scanner is performing as expected in that application.
5. If the scanner does not work in any application, this will ensure that the scanner is not working properly and you can contact the scanner manufacturer for a problem.
6. Restart Acrobat.

Restart the computer with the startup items disabled:

1. Some applications may cause system errors or freeze when running concurrently with Adobe Acrobat.
2. Before launching Acrobat, disable other applications, including startup items (items that start automatically with Windows).

1. Quit all apps.
2. Select Start> Run. Type msconfig in the open box and click OK.
3. In the System Configuration Utility dialog box, click the Start tab and select Disable All.
