Hello
(Need to re match or install the latest version of. NET framework on the computer)
If only one printer is installed on the computer, please open C: \ Windows \ System32 \ spool \ drivers \ x64 \ 3 on the computer, delete all files in folder 3, restart the computer and reinstall the printer driver for testing.
If the problem persists, please clear the temporary folder (temp) on the computer, turn off/uninstall defense software (such as 360 software) on the computer, and then reinstall the printer full version driver for testing.
Thank you.
