Printer - Specifications / Connectivity / Dual Band Network

The printer supports wireless as explained in the Specifications.

Sample

Product Specifications for the HP DeskJet 2720 All-in-One Printer (3XV18B)

Connectivity

Ports	1 Hi-Speed USB 2.0
Wireless capability	Yes, built-in Wi-Fi 802.11a/b/g/n
Storage device and direct print support	Storage devices not supported

The printer supports 5GHz or 2.4GHz - not at the same time.

Dual Band Network - Considerations

Reminders 

Some printers, particularly older models, only support 2.4GHz

Some printers support both 5GHz and 2.4GHz – but not at the same time

Regardless, if the printer won't work or cannot connect to your 5GHz frequency, try 2.4GHz.

If you are running a Dual Band Network,

 Check that the router is set up to broadcast all frequencies it supports.

Next,

If your router supports it,

 Create a separate SSID named network for each frequency (5GHz and 2.4GHz).

and

 Connect the printer to the SSID network on the frequency / band you want it to use.

In general,

• 2.4GHz is less fussy about obstacles and supports a longer distance (separation) between router and device (printer)
• 5GHz is faster

Printer Software - Windows

If the printer is on the network and able to connect to the SSID named network for the frequency you want it to use, Install the Full Feature Software to finish the connection.

The Full Feature Software includes the software for printing and scanning and access to the full range of features supported by the printer.

Printer - Full Feature Software - Install

If you have not done so, consider

• HP Full Feature Software / Full Driver printer software - supports printing and scanning from the web, printing in in other software and programs (for example, Word), and provides access to the full range of Printing Preferences / Shortcuts.  The full driver adds at least two shortcuts to the Desktop:  Printer Assistant and HP Scan.  If the printer model includes built-in Fax hardware, the software supports the setup and use of the Fax driver.  No Sign-in required.

If the full driver printer software is (already) installed but not working,

• Uninstall any printer software from Control Panel > icon view > Programs and Features
• Restart the computer and sign in.

Next,

• Check (for the Printer) in Devices and Printers  > If found, Right-Click Printer and Remove -- If any changes are made, that is, you remove anything, Restart the computer and sign in.

Next,

• If using a printer USB cable between the printer and the computer, disconnect the cable before installing the printer software.

• Download and Save the Full Feature Software installation package or the Easy Start Software

Installation

• After the software is installed, Restart the computer and log in

====================================

The installation of the full driver adds at least two shortcuts to the Desktop:  

Printer Assistant 

HP Scan

Open the Printer Assistant > tab Scan > Manage Scan to Computer > Enable
