Restart the printer and the computer or mobile device to clear possible error conditions. Restore Wi-Fi setup mode. Most printers with a touchscreen display or menu: Open the Wireless or Setup menu, select Network setup or Settings, and then select Restore Network Settings.
You need to ensure your HP printer has enough paper, ink, or toner, and it is not stuck on paper jam. Also, check the status of your printer cartridge and try replacing it with a new one if it is not good enough. In some cases, your HP printer stops printing after you replace its parts.
You may see a “printer offline” error if your computer can`t communicate with your printer. This can be caused by loose cable connections or an outdated printer driver or operating system. The HP Smart app (below) can automatically diagnose and resolve printer offline issues in Windows operating systems.
If you`re using a wired printer, make sure that the printer cable is properly connected from the printer to your PC. For wireless printers, check the wireless connection. Make sure the printer`s wireless option is turned on and available.
Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.
Reasons why your HP printer has ink but won`t print

This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.

Make sure your Wi-Fi network and printer setup meet connection requirements. Restart the printer and the computer or mobile device to clear possible error conditions. Make sure the printer is not connected to a computer with a USB cable.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
Restart your printer by turning it off, waiting 10 seconds, and disconnecting the power cord from your printer. Then, turn off your computer. Connect the printer power cord to the printer and turn the printer back on.
Make sure that both ends of the USB cable are correctly inserted into the computer and the printer. Try disconnecting and reconnecting the USB cable at both ends. Disconnect the printer and the computer and reconnect them. Try another USB port if available.
Remove any devices connected between the printer and computer (IE:USB Hub). Reseat the USB cable connecting the printer and computer by unplugging both ends, and plugging them back in. Check for a “Found New Hardware” Windows pop up installer.
1. On the printer display home screen, select the “set up” button (it looks like a gear). 2. Select “settings” > “device settings” > “reset settings” > “reset all” > “OK” and then “Yes.”
Reset. Resetting the printer stops printing and clears the current print job received from the active interface. You may want to reset the printer when there is a problem with the print job itself and the printer cannot print successfully.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
Regardless of which you choose, all of your applications will be deleted and any settings will be returned to their default. 9. If you choose “Remove everything,” you will also have to decide whether you want a completely clean drive or if you would like to keep the laptop and you aren`t planning on giving it away.
Some of the most common printer problems that most of us have experienced include paper jamming, slow printing, uneven printing, and wrong colour output. If you use your printer frequently, we know how annoying it can be to have persisting problems with the printer.
Among the more common technical issues that may bring down a printer are disconnected cables, malfunctioning routers, and low ink levels. Moreover, software problems such as interrupted connections or incorrect settings in your system`s drivers can also cause your printer to show up as offline.
Clean the print head, if necessary. Make sure the paper size, orientation, and layout settings in your printer software are correct. Make sure your document does not contain blank pages. If your printer software has a Preview option, you can check for blank pages before you print and remove them, if necessary.
If the LabelWriter appears as Unspecified or Unknown in Devices and Printers on Windows, it usually means that the computer has not identified that device as a printer yet.
Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.
In Windows, search for and open Add a printer or scanner . Click Add a printer or scanner, and then wait for Windows to locate available printers. If your printer is found, click it, and then click Add device to complete the driver installation.
Select the Start button, then select Settings > Devices > Printers & scanners. Under Add printers & scanners, select Add a printer or scanner. Choose the printer you want, and then select Add Device.
For the most part, a printer will appear “Offline” if your computer is unable to establish communication with the device. This could be due to factors like loose cable connections, outdated printer drivers, problems with important system services, etc.
