To put your HP printer back online, the key steps are to **check the printer’s connection**, **restart your devices**, and **adjust printer settings on your computer**:
1. **Check the connection:**
– For USB, ensure the cable is firmly plugged into both printer and computer.
– For Wi-Fi, verify the printer is connected to the correct network (not a guest or neighbor’s network). Check the wireless light on the printer—it should be steady, not blinking.
– For Ethernet, confirm the cable is undamaged and plugged correctly into both router and printer[1][2][3].
2. **Restart devices:**
– Turn off and unplug the printer.
– Restart your computer and router/modem, waiting 30–60 seconds for the network to reset.
– Turn the printer back on and try printing again[1][2][3][4].
3. **Set printer online in system settings:**
– On Windows, go to Control Panel or Settings > Devices > Printers & Scanners.
– Right-click your HP printer and *uncheck* “Use Printer Offline” (or in Print Queue, disable “Use Printer Offline” mode).
– Set the HP printer as the default device to ensure your PC sends jobs to it[1][2][3][4].
4. If problems persist, run **HP Print and Scan Doctor** (HP’s official diagnostic tool) to detect and fix issues automatically[4].
Following these steps typically resolves the offline printer status and gets the device back online for printing.
