Invalid WPA passphrase on an HP printer means the printer rejected the WiFi password the wizard sent — or the router rejected the join. It is not a driver error. Easy Start may still “find” the printer and then fail at this step.
Fix the passphrase first
- Type the password on a phone that is already on that WiFi to confirm it. Then enter it on the printer slowly; HP panels often swap 0/O and 1/l
- If the password has spaces or symbols, try a temporary simple password (letters and numbers only), join the printer, then change the router password back and update the printer
- Use the 2.4 GHz SSID. Most DeskJet, Envy, and OfficeJet units cannot join 5 GHz during setup and will throw a passphrase or association error on a 5 GHz-only name
- Split the router’s mixed 2.4/5 name into two SSIDs for setup. After the printer is online, you can hide the extra name if you want
WPA3, hidden networks, and filters
- WPA3-only: many HP inkjets only speak WPA2-PSK (AES). Enable WPA2/WPA3 mixed or WPA2 on the 2.4 GHz network for the printer
- Hidden SSID: enter the name exactly, including case. Hidden networks plus a typo look like a bad passphrase
- MAC filter / AP isolation: allow the printer MAC from the config page, and turn off guest isolation so HP Smart can see it afterward
If the printer never appears in Easy Start at all, that is discovery, not WPA — use Easy Start cannot find printer. After it joins, full WiFi steps are in HP WiFi not connecting.
After it accepts the password
- Wait for a solid wireless icon, then print a network configuration page
- Confirm the SSID on that page is the 2.4 GHz network you intended
- Add or refresh the printer in Windows/Mac by IP if HP Smart still searches
