摘要

A device comprises an evaluating unit having a tabulator and printer 20 for issuing a cash slip 19 bearing details of a sales transaction at least some of which are computed by unit from data set by tabulator and optionally a weighing pan. Cash slip 19 has unvarying information e.g. name of the firm variable information e.g. details of the transaction. Printer 20 incorporates a single dot matrix printing mechanism 21 which prints both sets of information. Mechanism 21 may be controlled to print the unvarying information when the preceding sales slip is removed. This function is sensed by feeler member 55 which actuates switch 54 to recall the fixed heading data from PROM 47. The variable information is printed without reliance upon PROM 47. PROM 47 is contained in an insert 46 which is interchangeably located in a pocket 45 whereby the nature of the unvarying information can be changed by replacing insert 46. A method of programming the PROM starting by recording original artwork with a video camera is disclosed (and shown in Fig. 7).
