Welcome to the HP Support Forums!
On the printer, is the wireless light blinking or is it on and steady? Was there any break in the wireless connection from two days ago, such as a power outage, or an unplugged power cord to the router or printer?
If not, the printer might need a firmware update. Go to Updating Firmware on the Printer > Update directly from the printer for the steps to check and update the firmware, if necessary.
Let me know if that helps!

Alternatively, you can connect to the printer using WiFi Direct connection.
This connection type (Wifi Direct) connects your Mobile device/computer Wifi directly to your printer and does not requires Wifi Router and is the preferred way i would use PROVIDED i do not need to continue the connection to the Wifi router network for surfing.
Do also remember to reconnect back to your WIFI router network to get internet connection after printing.
The password to connect to your printer Direct Wifi is either in the front panel display of the printer or you need to print it out by holding the WIFi button for 3 sec. Hope this helps.
