I recently had some issues with my printer not working on my home network and during the troubleshooting process I wanted to remove the printer port so I could reinstall the printer all together. The issues ended up being stupidity on my part for adding a temporary device on my network that had the same IP address of the printer so I was able to easily get that resolved once I figured it out by checking the MAC address associated to the IP in question using ARP. I did want to share how I was able to forcefully remove the printer port in Windows 7. These instructions will not only work for Windows 7 but will also work for other Windows versions including Windows Vista and Windows XP. Follow the instructions below to forcefully remove a printer port.

The easiest way to configure a static IP on the HP Photosmart C5100 is via the web interface. You probably do not know to the IP address of the all-in-one printer since you are just now configuring the static IP and if it is currently on the netork then it has received a dynamic IP address via DHCP (Dynamic Host Configuration Protocol). Regardless its an easy process which I will explain step by step below.

1. Locate IP Address: First we will need to locate the current Internet Protocol address of the printer. Look in the properties of the printer and look at the Ports tab to see if there is an IP address specified. If there is not then you can print a test page, bring up a command prompt, and type “arp -a”. You should notice a couple different IP addresses of which one should be associated with a Physical Address that begins with 00:19:BB which is Hewlett Packard. Once you have located the IP address take note. It should be an address where the first three octets begin with 192.168.0.

The arp cache of the Fortinet 200A can be cleared by typing the below command into the console.

Below shows how to display the arp table in a Fortinet 200A device running FortiOS version 3.0 or higher.

Short Answer: Type “get system arp” from the CLI

You can just type “get sys arp” from the CLI of the Fortinet 200A to get the ARP table. If you are running a previous version of FortiOS you can try the other two following options to display the ARP table.

FortiOS version 2.8: diag net1 neighbor list
FortiOS version 2.5: get sys inter
