need help setting up a printer

[Nharper13]

I just bought this second hand and would like to set it up. I connected it to my home WiFi, and my computer sees it on my printer list, but it says its offline. I have tried downloading the HP apps on my computers and the same thing happens, itll show up then will be offline. I will try to redo the connection and then it wont connect at all. I have downloaded software and firmware from the HP website and plugged the printer into my laptop to install and update that way, but it fails every time. I have done a factory reset on the printer and the network settings on the printer, all my paths lead down the same way. What am I doning wrong, what could I try that is different? It is not close enough to a router on my home mesh WiFi network to plug into directly, thats why I want it set up WiFi only.

Hi @Nharper13, a second-hand Color LaserJet Pro MFP M283 often still has the previous owner's network settings, which makes it appear offline.

Option 1 – Reset the network settings and reconnect

1. On the printer's touchscreen, open the Setup/Network menu and choose the option to restore network settings (the exact wording can vary by firmware).
2. Restart the printer.
3. Install the HP app from https://123.hp.com and add the printer, keeping the PC on the same 2.4 GHz Wi-Fi network.

Option 2 – Add it using its IP address

1. Print a Network Configuration page from the printer's Reports menu and note the IPv4 address.
2. In Windows, go to Settings > Bluetooth & devices > Printers & scanners > Add device > "Add manually" > "Add a printer using an IP address or hostname" and enter the IP.
3. Install the full driver from https://support.hp.com/drivers when asked.

If it still shows offline, please tell us whether you can open the printer's IP address in your browser.
