If you are able to access the EWS and use your printer with the firewall turned off, you need to reconfigure your firewall settings to allow the computer and printer to communicate with each other over the network. For more information, see Configure your firewall to work with printers.

If you are able to access the EWS, but are still unable to use the printer even with the firewall turned off, try enabling the firewall software to recognize the printer.

Step 4: Make sure the printer is online and ready

If you have the HP software installed, you can check the printer’s status from your computer to see if the printer is paused or offline, preventing you from using it.

Click Start, click Control Panel, and then double-click Printers.

2.If the printers on your computer are not being displayed in Details view, click the View menu, and then click Details.

3.Do one of the following, depending on the printer status:

a. If the printer is Offline, right-click the printer, and click Use Printer Online. b. If the printer is Paused, right-click the printer, and click Resume Printing.

4.Try using the printer over the network.

Mac OS X

1.Click System Preferences in the Dock, and then click Print & Fax.

2.Select the printer, and the click Print Queue.
