Check to see if the firewall software is blocking communication

If you cannot access the EWS and are sure both the computer and HP device have active connections to the same network, the firewall security software might be blocking communication. Temporarily turn off any firewall security software running on your computer and then try to access the EWS again. If you can access the EWS, try using the HP device (for printing or scanning).

If you are able to access the EWS and use your HP device with the firewall turned off, you will need to reconfigure your firewall settings to allow the computer and HP device to communicate with each other over the network.

If EWS is accessible and some of the HP functions are still not available, the following list of files should be added to the Trusted Programs list of your firewall program:

•hpiscnapp

•hpqkygrp

•hpqsplfix08

•hpsjrreg.exe

•hpqtra08.exe

•hpqdirec.exe

•hpqste08.exe

•HPZipm12.dll

•HPZinw12.dll

•hposfx08.exe

•hpospd08.exe

•hpofxs08.exe

•hpzwiz01.exe

•hpqvwr08.exe
