Full Answer

Since all HP wireless printers have a unique MAC address that identifies the device on the network, they sometimes go offline or become unable to establish a connection because the wireless router uses MAC address filtering. This filtering keeps blocking the wireless printer as long as its address is not present on the list of approved devices. In this case, the problem can be fixed by "whitelisting" the MAC address of the wireless printer or by disabling the MAC address filtering function altogether.

HP wireless printers tend to go offline if the wireless router is defective or doesn’t maintain signal over long ranges. The wireless signal can also be obstructed by walls and various objects. This problem can be fixed by placing the wireless router and printer closer together or moving objects which might cause the interference such as large appliances or devices connected to the wireless network. Alternatively, a person can modify the channel of his wireless router or extend the range and power of the signal with wireless access points to fix the problem.
