The report is due, the label needs printing, or the children need a worksheet for school, and suddenly the Mac insists the printer is offline. If “printer not working with mac” is what has brought you here, the good news is that this is usually fixable without replacing either machine. The less good news is that a printer problem can have several causes, from a loose Wi-Fi connection to an old driver left behind after a macOS update.
The quickest route is to work through the basics in the right order. That avoids changing lots of settings at once and makes it much easier to see what has actually solved the problem.
When Your Printer Is Not Working With a Mac
First, establish whether the printer itself is ready. Check that it is switched on, has paper, ink or toner, and no warning light or message on its display. If it has a screen, look for a Wi-Fi symbol and confirm that it is connected to your usual home or office network.
A printer can look perfectly healthy while being connected to the wrong network. This commonly happens after changing broadband provider, replacing a router, or pressing the Wi-Fi setup button by accident. A printer connected to an old network cannot be found by a Mac on the new one.
It is also worth printing a test page directly from the printer, if it offers that option. If the test page will not print, the fault is likely with the printer, its consumables or its network connection rather than your Mac.
Check the Mac and printer are on the same network
On your Mac, open System Settings, choose Wi-Fi, and check the network name. Then compare it with the network shown on the printer. The names need to match exactly.
Many modern routers offer both 2.4 GHz and 5 GHz Wi-Fi. Macs can use either, but some older printers only support 2.4 GHz. Usually the router handles this automatically, but separate network names can cause confusion. A guest Wi-Fi network is another common culprit because devices on it are often prevented from talking to each other.
If you use a VPN for work, switch it off temporarily and try printing again. Some VPNs route network traffic in a way that stops the Mac seeing a local printer. Do not leave it switched off if your employer requires it, but it is a useful test.
Clear a Stuck Print Queue
A single failed print job can hold everything else up. Open System Settings, select Printers & Scanners, choose your printer, then open the print queue. If you see a job marked as paused, stopped or waiting, cancel it before trying again.
If several old jobs are sitting in the queue, cancel them all. Then restart the printer and try a short document, such as a one-page note, rather than immediately sending a large PDF or a batch of photos.
A job may become stuck because the printer briefly lost its Wi-Fi signal, ran out of paper, or was turned off while the Mac was still sending data. Clearing the queue does not affect your documents. It simply removes the instructions the Mac has been unable to pass to the printer.
Restart in the right order
Restarting works best when it is done in sequence. Turn the printer off, wait around 30 seconds, and turn it back on. Restart the Mac afterwards. If the printer is wireless and still appears offline, restart the router too, allowing it a few minutes to reconnect fully.
This may sound basic, but it refreshes the network addresses used by the router, Mac and printer. It is particularly effective after a power cut or when a printer that worked yesterday has unexpectedly disappeared today.
Remove and Add the Printer Again
If your Mac can see the printer but refuses to print, removing it and adding it again often rebuilds the connection cleanly. Go to System Settings, open Printers & Scanners, select the affected printer and remove it. Then choose Add Printer, Scanner or Fax and wait for your printer to appear.
Where possible, choose the AirPrint option. AirPrint is built into macOS and supports a large number of current printers without separate software. It is normally the simplest and most reliable choice for everyday documents, photos and basic scanning.
There is a trade-off. Manufacturer software can provide extra features such as advanced colour controls, booklet printing, ink-level alerts or specialist scanning options. If you need those functions for business paperwork or high-quality photo printing, use the correct software from the printer manufacturer. Avoid generic driver-download sites and so-called Mac cleaning tools, as they can be misleading and occasionally bring unwanted software with them.
For a printer connected by USB, try a different cable or USB port before removing the printer. Cables do fail, and USB adapters can be less reliable than expected, especially with older printers.
Check Drivers After a macOS Update
A macOS update can expose an issue with an older printer driver. The printer may still show in the list, but print jobs do nothing or produce pages of odd characters. This is more likely with printers that are several years old, or specialist devices such as label printers, receipt printers and older office multifunction machines.
Check the printer manufacturer’s support information to see whether your exact model is supported by your version of macOS. If it is, install the current driver or use AirPrint if it is available. If it is not supported, there may still be a workaround, but it depends on the model and the features you need.
For example, an older printer may work adequately through AirPrint for ordinary black-and-white documents, but lose double-sided printing or its scan-to-computer function. For a household printer that may be an acceptable compromise. For a small business relying on labels, invoices or scanned records, it may make more sense to repair, reconfigure or replace the device.
Reset the printing system only when needed
macOS has a more thorough option called Reset Printing System. It removes all printers, saved print queues and related settings, allowing you to start afresh. It can resolve stubborn problems where multiple printers have been added over the years or the printer list has become confused.
Use it with care. You will need to add every printer again afterwards, including any office printer or label printer you use. It is a sensible next step when the usual checks have failed, rather than the first thing to try.
Do Not Forget the Scanner
On an all-in-one printer, printing and scanning are separate functions. It is quite possible for one to work while the other does not. If printing is fine but scanning has stopped, open Image Capture on the Mac and see whether the scanner appears there.
If it does not, restarting the printer and re-adding it may help. Older scanners sometimes need manufacturer software, especially after a major macOS upgrade. This is one reason it helps to know the exact printer model rather than relying on a name such as “Office Printer” in the Mac’s settings.
When It Is Time for Hands-On Help
If the printer keeps dropping offline, only works from one Mac, or has stopped working after a broadband or macOS change, it is often quicker to have someone look at the whole setup. The problem may sit between the router, printer settings, Mac software and an old driver, rather than being one obvious fault.
For home users, this can be particularly frustrating when several family devices need to print. For a Dorset business, a temperamental printer can mean delayed invoices, labels, forms and customer paperwork. North Dorset Mac Man can diagnose the issue at your home or workplace, explain what has gone wrong in plain English, and help make the setup dependable again.
Before arranging support, make a note of the printer make and model, your macOS version, and any message shown on the printer or Mac. That small amount of information can save time. More importantly, do not let a stubborn printer turn into a day-long battle – a calm, methodical check is usually all it takes to get the pages moving again.
