If your HP printer is offline on Windows 10, follow these steps to bring it back online. First, check the printer’s power, paper, and ink levels. Ensure all cables are connected or the Wi-Fi is stable for wireless printers. Open Control Panel > Devices and Printers, right-click your HP printer, and uncheck “Use Printer Offline”. Restart the Print Spooler service and update or reinstall the printer drivers from HP’s website. Set the printer as default and run HP Print and Scan Doctor for troubleshooting. If the issue persists, visit HP Support for expert assistance. Get your printer working smoothly again!
