1. Possible causes and solutions for the printer driver to be unusable:
Reason 1: The driver is corrupted or expired
If you find that your printer driver isn't working, it may be because the driver itself is corrupted or out of date. In order to solve this problem, it can be solved by updating the driver, reinstalling the driver, using a generic driver, or updating the Windows system files. First, tap on "Start Menu" and select "Devices and Printers", then "Add Printer" and select "Add Local Printer". Select the TCP IP option in the new port and enter the printer hostname and port name. Finally, once you have chosen to set the address and installed the driver, the printer will work fine.
Reason 2: Driver conflict
When installing multiple printer drivers, driver conflicts can occur. You can try uninstalling any non-essential drivers first, and then reinstall the ones you need. In addition, you can also use Microsoft's ShoworHideUpdates tool to prevent the installation of printer driver updates to avoid driver conflicts.
Reason 3: Operating system or application update
Sometimes, an update to the operating system or application can also cause the printer driver to become unusable. At this point, you can try rolling back the update to ensure compatibility of the operating system and application with the printer driver.
Reason 4: Network issues
An unstable or slow network connection may cause the printer driver to become unusable. Network issues can be resolved by checking network connections, modifying network settings, cleaning up network caches, and more.
Reason 5: The driver version is not compatible
The printer driver needs to match the operating system and printer model, and if the driver version is not compatible, it will also cause the driver to be unusable. When selecting and installing drivers, make sure you select the correct driver version.
2. When dealing with the problem that the printer driver cannot be used, you need to pay attention to the following points:
1.First check if you have the latest version of the driver installed and check if the driver has expired.
2.Confirm that you have more than one driver installed, and if so, try removing unnecessary drivers to avoid conflicts.
3.See if there are any updates to the operating system or application that are causing the driver to be unusable.
4.If you can't resolve the issue by updating the driver or reinstalling the driver, you can try rolling back the update and checking that your network connection and driver version are correct.
5.If none of the above methods solve the problem, you can consider contacting the printer manufacturer or technical support team for more professional help.
