Windows Printer Error 0x0000007a
What it means
A network printer connection error in the same family as 0x0000011b, tied to how Windows handles shared print connections after a security update. Connecting to the printer by its IP address usually works around it.
A full step-by-step guide is on the way
We publish guides only after checking each step against the manufacturer's own documentation, so this one is still being written. In the meantime, if the code relates to a jam or an obstruction, switching the printer off, unplugging it for a minute, and checking for anything stuck resolves a large share of cases.
Different code or problem?
Switch off and unplug a printer before reaching inside it. If a fault involves the power supply or internal electronics, or the machine is under warranty, contact the manufacturer or a qualified technician. Full disclaimer.
