## Maintenance
If you need new ink, don't buy HP ink. There are cheaper alternatives such as [952 XL Ink on Amazon](https://www.amazon.com/OfficeWorld-952XL-Cartridges-Combo-Pack/dp/B08F2CBQDB/ref=sr_1_21_sspa?crid=2GK9D4PUKVQ7P&dchild=1&keywords=hp+952+ink+cartridges&qid=1599573448&sprefix=hp+952+ink+%2Caps%2C911&sr=8-21-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyM0xTVkU5N1c1SFNEJmVuY3J5cHRlZElkPUEwNDkxMDk0MUExT0xDSzIySEhMSSZlbmNyeXB0ZWRBZElkPUEwNzkyNjIxMVVIRVNLN1pTSkVOSSZ3aWRnZXROYW1lPXNwX210ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=)
## 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.
