The printer is online but my laptop says offline.
The printer may have changed IP address, the laptop may be on a guest network/VPN, or the print queue/driver may be stale.
Printer IP; same subnet; guest isolation; driver/queue; mDNS.
Printer/OS support if network reachability is good.
Show the technical detail
On a managed Wi-Fi plan
Reserve IP only if justified; confirm local reachability first.
On another provider's router
Use hub device list for IP; OS/printer support handles driver.
What to be careful of
Do not open internet ports for local printing.
