A printing device ( 11 ) for printing receipts ( 12 ), each bearing constant data ( 41 a) that render the receipt ( 12 ) identifiable, and variable data ( 41 b), indicating the operations to be documented on the receipt in question, comprising: a roll ( 16 ) of thermal paper suitable for feeding a continuous ribbon ( 16 a) of thermal paper a first ink jet printhead ( 22 ), and a second thermal printhead ( 23 ), in which the first ink jet printhead ( 22 ) is provided for printing on the thermal paper ribbon ( 16 a) the constant data ( 41 a) due to figure on a new receipt ( 12 ), independently from and prior to the relative variable data ( 41 b) becoming available, and in which the second thermal printhead ( 23 ) is provided for subsequently printing the variable data ( 41 b), once available, so as to complete printing of the new receipt ( 12 ). The printing device is particularly useful, making the printing and issue of a receipt faster, after the relative variable data have been input, thereby reducing waiting time for the user that the receipt is to be issued for.
