Printer Not Responding: How to Fix It (Every Cause, Step by Step)

A loose or damaged cable is the single most common cause of a printer going unresponsive on a wired setup, and it’s the one people skip because it feels too obvious. Unplug the USB cable from both the printer and the computer, inspect both ends for bent pins or debris, and reseat it firmly. If you’re using a USB hub, plug directly into the computer instead — hubs are a frequent source of intermittent connection drops.

For printers on a wired network connection, check the Ethernet cable the same way, and confirm the small link light on the printer’s network port is lit. If you’ve been using the same USB cable for years, it’s also worth testing with a fresh one; internal wire fraying doesn’t always show from the outside.

Print spoolers and printer firmware both keep small caches of job data in memory, and either one can get stuck holding a corrupted entry. A full power cycle clears that memory in a way that simply canceling a job doesn’t. Turn the printer off using its power button, unplug it from the wall for about 30 seconds, then plug it back in and power it on. Restart the computer separately rather than just putting it to sleep, since sleep mode doesn’t reset the print spooler service.

Wait for the printer to finish its full startup sequence — you’ll usually see the display cycle through a self-check — before sending another print job. Restarting devices in the wrong order (computer first, printer still booting) is a common reason people think this step “didn’t work” when it actually just needed more time.

If an earlier print job failed partway through, it can sit in the queue as a corrupted entry that blocks every job behind it — including the one you’re trying to send now. On Windows, open Settings > Bluetooth & devices > Printers & scanners, select your printer, open the queue, and cancel every listed job, even ones that say “completed.” On Mac, open System Settings > Printers & Scanners, click your printer, and remove any stuck jobs from the queue window the same way.

If a job refuses to clear through the normal interface, restart the Print Spooler service (Windows) or reset the printing system (macOS) — both options are available without needing to reinstall anything. Once the queue shows zero pending jobs, send a fresh single-page test print rather than the original document, so you’re not re-queuing the same corrupted file.

It’s easy to end up with two entries for the same physical printer — one for a USB connection and one for Wi-Fi — especially after a driver update or a network change. If your document is being sent to the wrong entry, the correct printer sits idle and appears to be “not responding” even though nothing is actually wrong with it.

Open your printer settings list and look for duplicate names, often distinguished only by a small suffix like “(Copy 1)” or a different connection type. Delete the duplicate you’re not using, and set the remaining one as the default. On Windows, also make sure “Let Windows manage my default printer” is turned off if you print to the same device every time, so it doesn’t silently switch on you.

Wireless printers drop off the network more easily than most other smart devices, largely because their Wi-Fi radios are lower-powered to save on cost and heat. If your printer previously worked and now shows “not responding” only over Wi-Fi, start by confirming it’s still connected to the same network your computer is using — dual-band routers sometimes place devices on the 5GHz band, which has a shorter range than 2.4GHz.

From the printer’s own control panel, open the network or Wi-Fi settings menu, forget the current network, and reconnect using the password. Afterward, print a network configuration page (most printers offer this from the settings menu) to confirm it received a valid IP address. If the printer keeps getting a different IP address every time it reconnects, that’s usually what’s silently breaking the connection on the computer side — see our guide on connecting a printer to Wi-Fi for the full setup walkthrough, or the HP-specific Wi-Fi connection steps if that’s your brand.

Drivers are the translation layer between your operating system and the printer’s own command language, and an outdated or partially corrupted driver is a frequent cause of “not responding” errors that survive a full restart. Go to your printer manufacturer’s support site, search by your exact model number, and download the current full-feature driver package rather than relying only on Windows Update, which sometimes installs a generic, limited-function driver.

Before installing the new driver, remove the existing printer entry completely from your device list, restart the computer, and then install the fresh driver so it isn’t layering on top of leftover files. This full “remove, restart, reinstall” sequence resolves far more stubborn cases than simply running the installer over an existing broken driver.

Both Windows and macOS include a built-in diagnostic tool that checks the exact things covered in the steps above automatically — spooler status, port configuration, driver integrity, and network connectivity — and can fix several of them without any manual work. On Windows, open Settings > System > Troubleshoot > Other troubleshooters and run the Printer troubleshooter. On Mac, remove the printer from Printers & Scanners and re-add it, which triggers a similar automatic reconfiguration.

Let the troubleshooter run all the way through, since it often makes several small corrections in sequence rather than one single fix. If it reports that it made a change, send a new test print immediately afterward before doing anything else, so you can confirm whether that specific fix resolved it.

If the previous seven steps haven’t resolved it, the cause is likely inside the printer itself. A small paper fragment, a misaligned ink cartridge, or a sensor error can all make a printer refuse commands entirely — it isn’t ignoring your computer, it’s genuinely unable to process a job. Open every access panel the manufacturer lists (rear panel, top cover, duplexer tray) and check for torn paper, even small pieces near the rollers that aren’t visible from the main tray.

Reseat each ink or toner cartridge fully until you hear or feel it click into place, since a cartridge that isn’t fully seated can trigger a false “not responding” state on many inkjet models. If the display shows a numeric or lettered error code, look it up in your printer’s manual before continuing — some codes mean “power cycle,” while others mean “the print head needs professional service,” and treating the two the same wastes time.
