ER-A420 Tax Detail on Receipt

Hello Forum,

I can't seem to find where to update the tax text as it appears on printed receipts. I bought the cash register used. When printing receipts they show tax as HST8%C $xx.xx. I've set the tax rates to 13% and they calculate as expected but receipts still shows as 8% text displayed. How can I change the text displayed for tax on the receipts. I could not locate details in the manual.

Thank you in advance.
