Mac doesn't recognize printers - what to do?
If Mac OS no longer recognizes your printer, the device drivers are mostly to blame. This practical tip shows you how to fix the problem.
Step 1: check all connections
Before you go to the trouble of troubleshooting, check your printer's connections to your Mac.
- So make sure the printer is turned on and connected to your Mac.
- With a network printer, a faulty WLAN connection could also be the problem. Connect your printer to your network again here.
Step 2: is the printer compatible with Mac OS?
Apple has a constantly updated list of supported printers on its own website. You only need the model number of your device - you can usually find this on the bottom or inside the printer.
- Open the Apple list and start the search function of your browser with the key combination [CMD] + [F]. Now enter the model number of your device. The browser then automatically jumps to matching entries in the list.
- If your printer is included in the list, you can also immediately see the functions of the printer driver. In the three right columns you will see the letters "D", "F" or "S". Depending on the letter, you can use your device and Mac to "print", "fax" or "scan". If your model is not on the list, Mac OS does not officially support your hardware.
- For precise questions, it is best to contact the manufacturer of your printer.
Step 3: update printer software on Mac
If you are unable to connect to your printer despite the entry in the list, you should update your system. With every software update, Apple also provides new printer drivers.
- Click the Apple logo in the toolbar at the top left.
- If you open the entry "Software update", you will see all available updates for your system.
- Click the "Update" button to download the latest version of Mac OS. Then install the new system - your Mac will restart.
- You can then search for new printers in the "Printers" settings. Your connected device should now be recognized.
Step 4: reset the printing system - how it works
If you are unable to establish a connection despite the latest software and compatible printer, you should reset the printer system. To delete and reinsert all installed printers:
- Open the "Print & Fax" area in the settings. With a right click in the list of installed printers, you call the function "Reset".
- Close the warning message that appears with "OK". Mac OS will then reset the printing system; the printer list should be empty.
- With a click on the "+" at the bottom left, you can now add and use your printer again from a list of available devices.
If you need a document urgently, you can also print it quickly using the iPad.
