If your HP printer is not printing, the common troubleshooting steps include:

1. **Clear the print queue** to remove any stuck print jobs. You can do this via the printer settings on your computer by opening the print queue and canceling all pending jobs[1].

2. **Restart both the printer and your computer**, unplugging the printer for at least 60 seconds before powering it back on, which can reset any temporary issues[1][3].

3. **Check printer connections**, ensuring USB cables are securely plugged in or for wireless printers that the printer and computer are connected to the same Wi-Fi network. Also, verify the wireless indicator on the printer is solid and not flashing, indicating a good connection[1][2][3].

4. **Inspect for paper jams, paper supply, and ink status.** Remove any jammed paper carefully and verify the printer has paper loaded correctly and sufficient ink[2][3][5].

5. **Reinstall or update the printer drivers.** Remove old drivers via Control Panel and download the latest ones from HP’s official support page, as outdated or corrupted drivers can cause printing failures[1][3][4].

6. **Set your HP printer as the default printer** on your computer to ensure print jobs are sent to the correct device[4].

7. **Use HP Print and Scan Doctor**, an automated diagnostic tool from HP that can identify and fix many printing issues efficiently[1][3].

These steps address the most common causes such as connection problems, print queue errors, hardware issues like ink or paper jams, or driver/software glitches. If after these actions the printer still does not print, contacting HP support or a professional technician may be necessary[3].

In summary, start by clearing print jobs and verifying connections, restart your devices, check paper and ink, update drivers, and use diagnostic tools to resolve your HP printer not printing issue[1][2][3][4][5].
