I'm having issues detecting my printer (HP Deskjet 3630), OS Ubuntu 18.04. I've installed HPLIP and when I try to detect the printer via "Network/Ethernet" I get the following answer:

HPLIP cannot detect printers in your network.
This may be due to existing firewall settings blocking the required ports. When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall. For detailed steps follow the link.

I disabled the firewall but that didn't help.

I tried to change "Network discovery method" to mDNS/Bonjour and Avahi and didn't help neither.

  • According to HPLIP support page your printer is fully supported and does no need proprietary plug-in. How did you installed HPLIP? Do you know printer IP address? Can you reach its web-interface from web-browser?

  • I followed this guide: developers.hp.com/hp-linux-imaging-and-printing/downloads I know the printer's IP address. What do you mean by reach its web-interface from browser? How do I do that? Thanks!

    Possible duplicate of How to install latest HPLIP on my Ubuntu to support my HP printer and/or scanner? . About web-interface - you can simply visit http://192.168.x.y from your web-browser (where 192.168.x.y is IP-address of the printer).

  • Thanks, I didn't know I had that option from the web interface. I can make scans properly from there. However, if I try to print something the job is not completed. It remains "queued". But if I try to print form web interface it works just fine.

  • from the terminal lpinfo -v and tell us if the HP is seen; and run hp-setup and see what it reports; for our HP, we needed to do a usb setup first; before something changed and we could get the wireless connection going

Open HP Device Manager > Setup, then choose Network/Ethernet/Wireless network. Then, click Advanced Options.

Choose Manual Discovery and type the IP Address. After that, click Next.

Then, your computer should detect the HP Printer.


I went into Advanced and changed the discovery type. There are three protocols: SLP, Avahi and mDNS/Bounjour. Bounjour was the option that successfully discovered my printer, Officejet 86xx series (default was SLP).

  • This solution also worked for my HP Deskjet 2720

I resolved the same issue by installing the latest HPLIP from their website. It was 2 versions ahead (3.19.6) of the one prepackaged in the Ubuntu repositories (3.17) and their installer installed all the dependencies I needed. Afterwards the printer was detected without problems.


I have the exact same problem, I installed the latest hplip version from their website, still the printer is not detected at all, even though it's a well known hp model (2600 WiFi).

I solved it by navigating to CUPS site http://localhost:631— adding the printer there, instantly detect my 2600 WiFi and also automatically assign the right driver, sweet !

Note that you need to make sure CUPS is installed, nowadays it should be preinstalled otherwise run.

sudo apt install cups
