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 

@

 key. 

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.

changed with the mode key.  Please note when the register is recovered by a key entry, its key entry is invalid.  
After the recovery, start the key entry from the beginning.
