A computer recognizes some printer through plug-and-play capabilities, but there are instances where it fails to detect the printer. Since these are usually equipped with a USB-connected plug, all you need to do is insert it in a USB port. As a consequence, the device fails to pick up a printing request, pending the document in the printing tray. However, this issue can be solved easily with various methods.
If you get the printer not connected error, certain fixes will help you be able to print again. Multiple scenarios cause this issue. One may be a faulty USB cable that prevents the printer to be detected by the computer. It could also be that the driver for the device is missing or corrupted. Malware may also block the system from recognizing the printer as a plugged peripheral device.
Whether the printer isn't detected by attaching the cable or over the network, here are some fixes you can try to solve the issue.
a. Restart the printer
Click the printer's power off to shut it down, and then press to power on again. Wait a few moments to complete the process.
b. Check the printer's connection issue
Perform a physical inspection of the printer's USB cable to see if there are any cuts or breaks. Make sure that it is connected correctly and firmly. You can also check USB ports for any damages, and clean it with a soft brush indicated for cleaning computer parts. The dirt inside the USB port can accumulate and affect the function of these slots.
If you have a wireless printer, check the manufacturer's manual and follow the steps to reconnecting the printer to the Bluetooth or network. The process may vary from one manufacturer to another, so make sure to have the manual handy in cases like this. Also, you can check out the company's website since they usually have product manuals that can be downloaded online.
c. Check network connectivity
If your printer relies on the wireless network, it will never work when the network is down or having issues. Check your internet connection and troubleshoot if the need arises, and then try reconnecting the printer again.
Outdated printer drivers can cause the "printer not connected" error. Keep your drivers up to date to avoid these issues from arising. You can choose to update automatically or manually.
Go to your printer manufacturer's website and search for the specific driver of your printer model. You can use their site's search bar to do so. Since printer drivers are brand-specific, you cannot download just about any printer driver. Make sure that the driver you download is compatible with your Windows version, and is also up-to-date so as not to cause the said error.
You can use third-party software to detect your printer and Windows version, and it will find the specific driver for you.
