To keep your HP printer online, ensure it is properly connected to your computer or Wi-Fi network, set as the default printer, and configured not to be in “offline mode.” Restart your printer, computer, and router regularly to refresh connections. Checking and managing print jobs to avoid stuck queues also helps maintain online status[1][2][3].

Key steps to keep your HP printer online include:

– **Confirm the connection**: For USB printers, make sure the cable is securely plugged in; for wireless printers, ensure it is connected to the correct Wi-Fi network with good signal strength[1][3].

– **Set the printer as default**: This ensures your system recognizes the correct printer and avoids confusion with other devices[1][2].

– **Disable “Use Printer Offline” mode**: In Windows, go to “Devices and Printers,” right-click your HP printer, select “See what’s printing,” then under “Printer” menu, uncheck “Use Printer Offline”[3].

– **Clear the print queue**: Cancel any stuck or pending print jobs that could block new print commands[1][4].

– **Run HP diagnostic tools**: Use the HP Print and Scan Doctor tool to troubleshoot and fix connectivity and driver issues automatically[2].

– **Check port settings and Windows services**: Make sure your printer is not using a WSD port that can cause lock issues, and that related Windows services like “Function Discovery Provider Host” and “Function Discovery Resource Publication” are running and set to automatic[2][5].

– **Update firmware and drivers regularly**: Keeping software up to date helps prevent connectivity problems that cause the printer to go offline[3][4].

– **Address Wi-Fi signal issues**: Weak Wi-Fi can cause the printer to go offline intermittently—consider moving the printer closer to the router or using a Wi-Fi extender[3].

If issues persist, temporarily connect the printer via USB cable to isolate network-related problems[3].

Following these practices helps maintain your HP printer’s online status and reduces printing interruptions.
