Hey There, I am Sofia Carter. Following may be the reasons that the driver is unavailable printer hp: 1. Your printer is missing or has not yet been detected by your computer. 2. There's a chance the printer file is corrupted or destroyed. You can use the same method to troubleshoot the error in both circumstances. Remove the existing printer driver from your computer's control panel and install a new, up-to-date printer driver. https://www.hpprintersupportpro.com/blog/resolve-windows-10-printer-driver-is-unavailable-issue/
