HP are well known to regionalise their printers. This means that if you purchase a printer in the UK, and move to the US, the US inks will not work in your machine. A UK printer needs inks from the UK. Australian printers need Australian ink etc.
It was previously thought there was no way around this, and HP themselves advise you to purchase a new one which has causes issues for some customers.
However, never underestimate the power of the people! Michelle Sullivan, after moving from Australia to Malta, discovered her HP C7180 no longer worked. And she did not approve. In fact she pushed so much, she drew global attention to HP saying “wait, no, it is possible to re-regionalise your machine”.
How To Change Your HP Printer Region
Step 1
Phone HP customer service on 0207 660 0596.
Step 2
Ask for the steps to re-regionalise your printer. They will tell you the numbers needed off your printers Test Print.
Step 3
Give them the requested details and they'll provide a special code to enter in your printer settings. This will give a response code you read to them.
Step 4
Turn your printer off for 2 minutes. Restart it and your printer should have switched region.
You Can Only Do This Three Times
Try not to region hop too much, as HP limit it to three re-regionalise processes per printer.
