I believe this might help, not exactly familiar with this exact model but here it goes.
Receipt ON/OFF function
When you use the printer to issue receipts, you can disable receipt printing in the REG mode to save paper
using the receipt ON/OFF function. To disable receipt printing, press the Rkey in the OP X/Z position. This
key toggles the receipt printing status ON and OFF.
The register will print reports regardless of the receipt state, so the paper roll must be installed.
To issue a receipt when receipt ON/OFF function is set to OFF:
If your customer wants a receipt after you finalized a transaction with the receipt ON/OFF function being OFF
status, press the Rkey. This will produce a receipt. However, if more than 30 items were entered, the
receipt will be issued in a summary receipt.
Copy receipt
You can print a copy receipt by pressing the Rkey when the receipt ON/OFF function is in the “ON” status.
To realize this function, you must enable the function. Please refer to page 62 (Job code 63).

I don't have this particular cash register, But I took a look at the manual and I recommend the following:

A. Turn the cash register off.

B. Unplug it.

C. Remove the batteries.

D. Wait at least five minutes.

E. Initialize the cash register. This procedure was copied from thwe manual:

In order to operate the cash register properly, you must initialize it before operating for the first time. Follow this
procedure.

1. Insert the manager (MA) key into the mode switch and turn it to the REG position.

2. Insert the plug of the AC power cord into the AC outlet. The buzzer will sound
three times.

IMPORTANT: This operation must be performed without batteries installed.

3. The cash register has now been initialized. The register display will show
"0.00" and then “NO BATTERY”.

If the buzzer does not sound when the plug is inserted, the initialization has not been done
successfully. (This will occur when the voltage is high because you operated the cash register
before starting initialization.) Wait at least one minute after pulling out the plug and insert the plug
again.

F. Download trhe manual from here:

And proceed to program your sales tax (or VAT), departments, clerks, etc.
