Your HP printer may not be printing due to several common issues such as lack of paper, paper jams, empty or clogged ink cartridges, wireless connection problems, or outdated/missing printer drivers. Additionally, stuck print jobs or printer configuration errors can cause the issue[1][2][3][5].

Key steps to troubleshoot include:

– **Check paper and ink:** Ensure there is paper loaded properly with no jams, and the ink or toner cartridges have enough ink and are correctly installed[1][2][3].

– **Verify wireless or USB connection:** Confirm the printer is connected to your Wi-Fi network or computer. A flashing wireless light often indicates a connection problem[2][3].

– **Clear print queue:** Remove any stuck print jobs that might be blocking printing by accessing the printer queue on your computer and canceling all pending jobs[1][3].

– **Restart devices:** Power cycle your printer and computer to reset temporary software glitches[3][5].

– **Update or reinstall drivers:** Make sure your printer driver is up to date. If problems persist, uninstall and reinstall the latest driver from HP’s official website[1][3][5].

– **Run HP Print and Scan Doctor:** This free diagnostic tool from HP can automatically detect and resolve many printing issues[3][5].

If these steps do not resolve the issue, internal hardware problems like clogged printheads or printer malfunction could be the cause, in which case contacting HP support is recommended[4][5].
