Windows Cannot Connect to the Printer – Error 0x0000007c

As it turns out, even though security patches are essential for your computer, especially in a work environment, it doesn’t really bode well when it breaks some functionality. You can go about solving this issue by simply uninstalling the update that has uprooted it in the first place.

However, in order for that to work properly, you will also need to stop Windows updates for the time period.

Cancel Driver Installation Midway

Finally, if the above-provided solutions do not fix the problem for you, then you can try something that is slightly weird but has reportedly fixed the issue for a user.

Once you do this, and the printer connects successfully, go ahead and cancel the installation. After doing this, see if the problem still appears for you.
