I notified the moderator of the problem.
Changing the region code can be difficult as described here.
When an agent contacts you ensure that the agent is familiar with the OS you are using. If the agent is in a different time zone try to get one in your time zone. If that is not possible you may need to choose the best time to make a contact.
I read that only 3 or 4 region changes are allowed. It depends on which AI bot I ask.
You may need WhatsApp to work through the region reset procedure.
1. The printer should be connected using a printer USB cable to the computer.
2. You need to have the printer full feature software installed on your computer.
3. You need to have all the cartridges either from the region/country from where the printer was purchased originally or the new region/country to which you want to reset it to.
4. The cartridges must be genuine HP.
5. Make sure HP Smart App is installed.
6. If the printer is not under warranty, then the ink cartridges need to be in the warranty period.

Hi @Cd522,
Welcome to the HP Support Community.
Thank you for posting your query. I will be glad to help you.
I'd be glad to help you. Please note that HP Printers use different ink cartridges in different regions, and to use the ink cartridges sold in the current region, we need to change the region settings on the printer.
I request you to please get back to me with the following information, so that I can help you change the region settings on the printer.
Do you still have the ink cartridges for both regions
Do you have a printer USB cable?
Which OS is on the PC? Is it Windows or Mac?
Do you have the printer's full feature software and drivers installed on your PC?
Hope this helps!
I'm an HP Employee.
