Device for printing receipts using two printing units, particularly on thermal paper, and related printing method

Abstract

A printing device () for printing receipts (), each bearing constant data () that render the receipt () identifiable, and variable data (), indicating the operations to be documented on the receipt in question, comprising: a roll () of thermal paper suitable for feeding a continuous ribbon () of thermal paper a first ink jet printhead (), and a second thermal printhead (), in which the first ink jet printhead () is provided for printing on the thermal paper ribbon () the constant data () due to figure on a new receipt (), independently from and prior to the relative variable data () becoming available, and in which the second thermal printhead () is provided for subsequently printing the variable data (), once available, so as to complete printing of the new receipt (). 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.
