Any way you could help figure out why my printer isn't working? Since I got new internet?

Whoever set up the new Wi-Fi network presumably picked a new network name and new password.

They probably just left it all set at the router / firewall / gateway box at its defaults too, and called it a day.

This means you’ll either need to reset the printer network settings, or manually configure the printer for the new network name and new password using the printer control panel.

How to do any of this reset and reconfiguration depends on the specific vendor and model printer itself.

and I changed my google password....

Unless this is a Google printer, your Google password is only relevent for continuing to allow Google to collect your personal data and metadata. Not for printers and printing.

Related: While you’re reconfiguring the printer network settings, check for new printer firmware, too.

Related: It’s usually also possible to set up your own Wi-Fi network name and password, and to then continue to use that same name and password again in the next Wi-Fi network, if (when?) the router / firewall / gateway box inevitably gets replaced. That’s a little more advanced, but it means ypu don;t have to reset everything again, just reconfigure the one box for your preferred network name, rather than everything else adapting to that box.
