Maintenance
If you need new ink, don't buy HP ink. There are cheaper alternatives such as 952 XL Ink on Amazon
Troubleshooting
If the printer appears to be offline, try to use this HP Print and Scan Doctor application. Alternatively, you can use print from your iPhone, which works more reliably than printing from Windows laptops.
