The 0x000006e4 (RPC_S_CANNOT_SUPPORT) error is also a very closely connected one. Although it has a different error code, that’s much the same issue as 0x0000007c. When that error occurs, users can’t utilize network printing.

Microsoft released a Windows 11 KB5006674 patch update in October and November 2021. That update has triggered the 0x0000007c and 0x000006e4 networking printing issues for users.

Such a scan will tell you if your printer has a faulty or outdated driver or not. After scanning, most driver updater software enables you to automatically download and install new drivers for devices that need them. So, it’s usually easier to install new drivers with third-party driver updater software.

6. Remove and add the printer again
