HP P1109w: Changing wifi settings

Requirements

Make sure you have httpie installed. If you're using homebrew, you can easily do it so with:

brew install httpie

Start the web server

All changes are performed through a local web server. To start it, run the following command:

"/Library/Printers/hp/laserjet/p1100_1560_1600series/HP LaserJet Professional Utility.app/Contents/MacOS/HtmlConfig" 1008 4138

This command will open a page on your default browser, that may or may not load.

Updating wifi settings

With your printer connected via USB and with the web server running, issue the following command:

http --form POST 'http://localhost:5050/cgi-bin/ip_wireless_result.htm' 'ID 207'=1 'ID 208'=1 'ID 216'='WIFI NETWORK NAME' 'ID 217'=2 'ID 219'='WIFI PASSWORD' 

These are the fields you can use:

• ID 208 = Enable wireless (0 disabled, 1 enabled)
• ID 216 = Network name
• ID 217 = Security Mode (0 no auth, 1 = WEP, 2 = WPA/WPA2)
• ID 219 = Wifi password

Updating Bonjour settings

This is required if you want to use AirPrint with your Apple devices. With your printer connected via USB and with the web server running, issue the following command:

http --form POST 'http://localhost:5050/cgi-bin/ip_bonjour_result.htm' 'ID_b 168'=1 'ID 167'='Printer'

These are the fields you can use:

• ID_b 168 = Enable bonjour (0 disabled, 1 enabled)
• ID 167 = Bonjour name

Update network settings

With your printer connected via USB and with the web server running, issue the following command:

http --form POST 'http://localhost:5050/cgi-bin/ip_config_result.htm' 'ID 139'='Printer' 'ID_b 148.0'=14 'ID 151'=1 'ID_b 148.1'=2 'ID_b 148.1'=8

These are the fields you can use:

• ID 139 = Hostname
• ID_b 148.0 - IP address (14 automatic)
• ID 151 = Enable WINS Server (0 disabled, 1 enabled)
• ID_b 148.1 = DHCP (2 to enable)
• ID_b 148.1 = AutoIp (8 to enable)

These are the fields you can use:

• ID 139 = Hostname

Wow, I cannot thank you enough for this extremely helpful guide! This printer is great, but annoyingly keeps forgetting its settings or something every 18 months or so and I'm having to do this all over again. 😅
