This document is for HP consumer inkjet and LaserJet printers connected to a network with limited or no security.
HP does not recommend connecting a printer to an open network that is not secured behind a firewall or router. This increases the risk of other people accessing printer functions, printing unwanted pages, or worse. To avoid security issues, make sure the printer is connected to a secured network with a configured firewall or router.
HP recommends upgrading your printer to the latest firmware version. To obtain the latest firmware, go to HP Software and Driver Downloads and search for your printer model.
If you must connect the printer to an open network, change security settings to help reduce the risk of unwanted access.
Available settings and menu names vary by printer model and firmware version. Refer to your printer user guide for specific configuration options.
