## Troubleshooting
If the printer appears to be offline, try to use this [HP Print and Scan Doctor](https://support.hp.com/us-en/document/c04249080) application. Alternatively, you can use print from your iPhone, which works more reliably than printing from Windows laptops. You can also send a PDF to the following email [mailto:89ith27etcab@hpeprint.com 89ith27etcab@hpeprint.com].
