Can´t install network printer driver

[Diana60]

I am trying to install the network printer driver for my L7780 pro. After I download the software I get the assistant and click on the "network printer driver" option. After that I get an error message that the required USB settings and software are not installed although I do not want to install the printer as a USB printer. Any ideas?

3. Search Windows for devices, then click Devices and Printers in the list of results.
4. Right-click the icon for your printer , click Remove Device, then follow the on-screen instructions to complete the printer removal.
   If multiple icons exist for your printer, remove them all

Follow these steps. 

Setting Up the Printer for a Wireless Network in Windows for the HP Officejet Pro L7710, L7750, and L7780 All-in-One Printers

Introduction

This document contains instructions to install the product in an existing wireless network that uses an access point, such as a router. This type of network is called an infrastructure network. HP recommends the infrastructure type of network for wireless connection to your product.

 NOTE:

You can also use these instructions if you previously installed the software for a USB connection and now want to change to a wireless network connection.

IMPORTANT: Before you can install the product, your wireless network must already be set up. (To set up your network, follow the instructions that came with your particular access point.)

 NOTE:

If you set up device filtering on your access point, and need to find the IP or MAC address of your HP product, see Additional Information at the end of this document.

IMPORTANT: Before you can install the product, you must have the following information about the network:

• Network name: The network name is the SSID (Service Set Identifier).
• Password: WEP key or WPA passphrase

 NOTE:

To gather this information, you can ask the person who originally set up your network, see the documentation that came with the access point, or contact the manufacturer. HP cannot set up or change the network SSID, WEP key, or WPA passphrase.

The HP Print and Scan Doctor is a free tool to diagnose and resolve printing problems and to gather network information. To look up your network name and password, download and run the HP Print and Scan Doctor on a computer that has an active wireless connection to the network.

When you click the link, the HP Print and Scan Doctor downloads using your Internet browser download capabilities. After the tool opens, follow these steps to view your network settings.

1. Click Start on the Welcome screen.
2. Select your printer, and then click Next.
3. On the Menu bar, click Network, and then click Show Advanced Info.
4. Click Show Wireless Info.
5. In the Wireless Settings section, the SSID column lists the wireless network name, and the Network Key column lists the corresponding wireless network password.
