When a printer will not connect to a computer, the printer might be fine. The problem is often Wi-Fi, USB, drivers, old printer entries or a stuck queue.
Start by working out how the printer is meant to connect: USB, Wi-Fi, ethernet or app-based setup.
Connection basics
Run through the safe checks before you spend money, reset devices or start changing settings you may need later.
- Check whether the printer can print a test page from its own menu.
- If USB, try a different cable or port.
- If Wi-Fi, confirm printer and computer are on the same network.
- Cancel stuck print jobs.
- Check whether the computer has multiple copies of the same printer.
What the symptoms usually mean
Setup fails partway through every time
Usually points to
Most commonly the printer is trying to join a 5GHz network. The majority of home printers are 2.4GHz only, and many modern routers publish both bands under one name, so the printer cannot complete the handshake.
Best next step
Separate the bands temporarily in the router settings, or use the router's WPS button, so the printer has a 2.4GHz network it can actually see.
The computer never finds the printer during Add Printer
Usually points to
Network discovery is switched off, or the two devices are on different networks - a guest network or an extender broadcasting a separate name is the usual culprit.
Best next step
Confirm both are on the same network name, then enable network discovery on the computer before searching again.
It connects by USB but not wirelessly
Usually points to
The printer's wireless side has never been configured, or it still holds credentials for a previous router.
Best next step
Run the printer's own Wireless Setup Wizard from its front panel to clear the old credentials and join the current network.

USB and Wi-Fi are different fixes
A USB printer depends on cable, port and driver. A Wi-Fi printer depends on network connection, router settings, discovery and driver. Mixing the two can create duplicate printer entries.
Old installs can point jobs nowhere
If the computer lists the printer more than once, it may be sending jobs to an old or offline entry. Cleaning those entries properly is often the fix.
Router changes often break printers
If the problem began after new broadband kit, the printer may still be connected to the old network. That needs network setup, not printer repair.
Do not reinstall endlessly
Repeated installs can create duplicate printers and make the computer harder to use. Clean out the old setup first.
Quick questions
Why does my printer show offline?
It may be using an old connection, wrong printer entry, stuck queue or network problem.
Can this be fixed remotely?
Often, if the computer can get online and the printer is already on the network.
Do you fix printer hardware?
I handle setup, connection, driver and queue problems. Mechanical faults may mean replacement is better.
