HPLIP

what network ports does hplip search printers on?

Asked by Gurjit Dhaliwall

I'm trying to setup a laserjet hp2035n using hplip and it can't seem to find the printer.

I'm operating in a highly controlled env where specific port opening requests need to be made.

1. What network ports need to be opened to allow hplip to find the printer?
2. Do we need to enable 'ping' to work to the printer for hplip to work?

Thanks.

Also ..can you confirm whether the printer needs to be 'pingable' for hplip to work?

Hi Gurjit,

We apologize for delay in our response.

Can you run 'hp-check' command in terminal and provide its full output here.

The network ports that we try to open are 427,5353 to discover the network printers.
Can you check if these ports are opened in your network environment.

Thanks,
Goutam

Hi Goutam

I've included the output of the hp-check utility below.
The printer we're having an issue with finding using hp-setup is : WPCA_CHK_PRINTER.

Q1. Can you comment on the following link which seems to suggest different ports required to be open?

Q2. Also, does the printer need to be 'pingable' for hp-setup to find the printer?

Hi Gurjit,

Ports 427,5353 are used by slp and mdns protocol to do network discovery of printers.

Port 9100 is used for printing
Port 161,162 are used by snmp protocol to

The printer needs to be pingable.

You can follow the instructions provided in http://hplipopensource.com/node/216 and let us know what is the output you get by running command.

snmpwalk -Os -c public -v 1 ip.address.of.printer 1.3.6.1.4.1.11.2.3.9.1.1.7.0

From hp-check log i could not find which linux distribution is being used. Can you tell us which linux distribution it is ?

Please go to the link http://hplipopensource.com/hplip-web/install_wizard/index.html.

Choose operating system as Red Hat Enterprise Linux and select version 5.0 and select the appropriate option and proceed. This should help you to download the hplip drivers for RHEL 5.

Sometimes ports are not supportable for that you have to check your port support drivers and reinstall it. Now it will hplip search printer on. To know more visit https://printerchatsupport.co.uk/hp-printer-support/

Can you help with this problem?
