can't see hpwifi printer

1chip · June 30, 2020, 6:53pm

I set up my hp 3830 on my destop usb and wireless. My laptop doesn’t see it as a printer, but it does show up as a wifi connection.
What do I need to do to get the printer working from the laptop?
Desktop and laptop both have leap 15.2.
I tried adding it in yast but wasn’t detected.

Hi
Is the cups service running? Temporarily disable the firewall and run hp-setup (if it needs a plugin, then run hp-plugin as your user first).

@1chip:

It may be that, the Avahi discovery isn’t working:

Are the following systemd Services enabled and running?

avahi-daemon.service; dbus-org.freedesktop.Avahi.service; avahi-daemon.socket

In ‘/etc/nsswitch.conf’, do you have a line like this?

hosts:          files mdns_minimal [NOTFOUND=return] dns

Yes cups is running

…and the firewall?

sudo systemctl status firewalld

Ok, so the printer is detected by the CUPS backends, but not by the HP utilities.

You can however run ‘hp-setup’ and configure manually with the IP address (192.168.1.5), or perhaps by it’s Avahi hostname (HP1860245ACB6A.local).

Thanks that worked finally

Good result.

deano_ferrari · June 30, 2020, 10:56pm

One more thing that I should mention - make sure that if the printer is assigned with a DHCP IP address, that you reserve it in the router (device acting as DHCP server) for this printer so that it doesn’t change unintentionally.

malcolmlewis · June 30, 2020, 11:02pm

Hi
I usually set a small range for DHCP somewhere in the range, then set a static ip address in the device (for HP just http://ip_address).

1chip · June 30, 2020, 11:09pm

ok will do. Started the firewall and printer works ok.

deano_ferrari · June 30, 2020, 11:44pm

Yep, that’s another option. Either way…
