[wikikang]

I bought HP 8720 printer at amazon of USA.

I am use this in korea now.

Firmware Ver.: WMP1CN1716AR
I have updated using firmware from HP homepage directly when I received.

and I changed language from English to Korean on setup menu.
and attached Application icon on menu using Apps icon(Private print/google drive/scan image/family search/public print .....).
But language and Apps restored factory setting automatically at displayed menu when system rebooting .
It was disappeared korean language and Apps icon.

Let me know how to setup language and the method using Apps.

and I did semi-full-reset using lit menu(Hidden display menu) many times. and did partial reset, too.

I asked to HP solution center(USA) but they can not solve. 

I did call Korean solution center, they can not solve this issue, too.

HP solution center(USA) said th me  ask this site.

Greetings @wikikang, 

Welcome to HP Forums and Thanks for the post. 

I understand that you are looking to change the language on the printer, is that right?

Kudos to you for exhausting all the troubleshooting steps. 

Not to worry, I will be glad to assist you. 

Is the printer setup over wireless?

Are you able to make a copy on the printer?

If the printer is setup over wireless, recommend you get the IP address of the printer and try to change the language of the printer using the EWS page. 

Recommend you refer to this HP Article for assistance in changing the language on the printer. (Though your printer is not listed in the article, it would still help you get to the EWS page of the printer to change the language.)

Please click here for the user manual of the printer for assistance. 

Hope this helped.

thank you reply my question.

I wonder if you can solve this issue using contact your phone support.

you mean your HP has high tech level, right?

I did already test with your HP printer Assistant. but I think HP printer Assistanthe has tech. limited . 

but I'm in korea now , so I can not call to USA because telephone cost. ^^^

Can you call to me?

Thanks for the reply To the best of my knowledge, the tech support will not be able to call anyone outside of USA. Recommend you contact our chat support if you are able to call.
