Printer with wlan offline?

I want to print something (via wi-fi), but my laptop shows me that the printer is offline, even though it is turned on and wireless is also connected?

Offline is always such a thing where people despair. But no problem, nothing is broken.

Offline you can set any printer, so that no one can print, or only at certain times.

Hiding something in the printer settings you can choose online or share. Then he works again.
