Need your help please.
Since I have a new router, when I turn on my good old "HP Deskject 4500 wifi" all computers shows that the printer is offline.
Only when I restarted my router the printer is shown again.
Two important things:
1) It never happened with the old router.
2) In the router management application, when this happens, I cannot see the printer is connected. After the restart I can see it again.

Welcome to the HP Support Community.
Let's restore the network settings on the Printer:
Select Setup, select Network, and then select Restore Network Defaults.
Once done, set up the Printer with the new Wi-Fi:
1. On the device control panel, press the Setup button. 2. Press an arrow button to move to Wireless Menu, and then press OK. 3. Press an arrow button to move to Setup Wizard, and then press OK. 4. Follow the display instructions to complete the setup.
Let me know if this helps.
